a quotation taking n inputs from the stack and producing another quotation as output
n
a non-negative integer
Outputs None
Word description Defines a compiler transform for the optimizing compiler. When a call to word is being compiled, the compiler first checks that the top n stack values are literal, and if so, calls the quotation with those inputs at compile time. The quotation can output a new quotation, or f.
If the quotation outputs f, or if not all inputs are literal, a call to the word is compiled as usual, or compilation fails if the word does not have a static stack effect.
Otherwise, if the transform output a new quotation, the quotation replaces the word's call site.
Examples The cond word compiles to efficient code because it is transformed using cond>quot:
