It works like that in (Guile) Scheme too. Though, to be precise, ‘expand’ refers to the macro expansion phase, whether compiling or not. ‘compile’ is for “evaluate during macro expansion, but not only when compiling”. >[...] >i briefly tired to find the place where DEFINE is compiled to check this >hypothesis in the code, but i couldn't find it. In macro-expansion: • https://git.savannah.gnu.org/cgit/guile.git/tree/module/ice-9/psyntax.scm#n1370 (also see mentions of ‘define-form’) Evaluation: • Probably somewhere in https://git.savannah.gnu.org/cgit/guile.git/tree/module/ice-9/eval.scm • Perhaps somewhere in https://git.savannah.gnu.org/cgit/guile.git/tree/libguile/eval.c as well In Tree-IL: * https://git.savannah.gnu.org/cgit/guile.git/tree/module/language/tree-il.scm#n220 * https://git.savannah.gnu.org/cgit/guile.git/tree/module/language/tree-il.scm#n310 Also maybe see relevant optimisation code and other layers of the compilation tower.
