Indicates an operator has precedence over unmarked operators. When an operator is prefixed with this cmavo, it becomes automatically of higher precedence than other operators not so prefixed. If more than one operator has a bi'e prefix, grouping is to the right; multiple bi'e prefixes on a single operator are not allowed.
This is distinct from the use of mathematical brackets {vei} and {ve'o}.
Marks the mekso expression as using Reverse Polish (RP) notation. RP notation is always marked by an explicit fu'a at the beginning of the expression. Operators acting in RP are required to have two operands (though {tu'o} and {ge'a} can assist when using unitary and ternary operators respectively).
It seems quite arbitrary that operators acting in reverse polish notation are required to have exactly 2 operands. Especially considering that in polish notation, operators are allowed to have as many operands as they like. It does not make semantic sense for all operators (for example the negation operator, used in the example usage above) Though there is a problem in determining which operands belong to which operator, and the solution currently is quite elegant for usage, it lacks symmetry with forethought equivalent and seems contrived. Perhaps {ku'e} could have its use extended from separating groups of operands in forethought mode to doing it in RP mode too.
Joins a sequence of simple operands or bracketed full expressions into a vector. A vector may have any number of components. It's corresponding terminator {te'u} is elidable.
It is the only member of selma'o JOhI
This is the elidable terminator of operators when they are acting in forethought mode. It serves to distinguish where the operands of one operator end and another begin.
This flag converts letteral string or other mathematical expression (mex) operand into a mex operator. Its elidable terminator is {te'u}.
The CLL has the following observation: There is a potential semantic ambiguity in ma'o fy. [te'u] if fy. is already in use as a variable: it comes to mean "the function whose value is always 'f' ". However, mathematicians do not normally use the same lerfu words or strings as both functions and variables, so this case should not arise in practice.
Converts a sumti to a mex operand. Intended to allow dimensions to be embedding into mex expressions. It is also used for "folk quantifiers", also known as collective nouns. It precedes the sumti. Its elidible terminator is {te'u}.
The cmavo ``na'u'' makes a selbri into an operator. In general, the first place of the selbri specifies the result of the operator, and the other unfilled places specify the operands. Its elidible terminator is {te'u}. It is also used to construct questions about operators.
This comment applies exclusively to CLL example 18.18.1. I'm not sure if it therefore belongs here. The CLL example of this seems to be needlessly complicated (using the value of pi/2 where the function is undefined). I've changed the example here slightly to avoid any disputes about validity.
