Daishi Kato scripsit: > How do I expand the quasiquote macro in the environment?
The trouble is that in Chicken all environments share the same macros, so you are stuck with the definition of quasiquote unless you override it globally with a version that doesn't invoke ##sys#list or ##sys#cons. > I don't want to extend the environment to have ##sys#list. > Maybe, extending macroexpand? That doesn't help much; it's not the macroexpansion that's at issue, it's the eval that's done after calling macroexpand. That eval uses the current (dynamic) environment. BTW, Felix, the claim on the wiki that the interaction environment can't be extended appears to be false: [EMAIL PROTECTED]:~/mpron$ csi CHICKEN Version 2.736 - linux-unix-gnu-x86 [ manyargs dload ptables applyhook ] (c)2000-2007 Felix L.
