Yes, time and println are just const global bindings to generic function objects. I am kind of confused how to think of the hygiene of a macro: > - Should i be thinking in terms of what is returned as an expr from the > macro should not conflict with the code context where it is returned? > - Or should i be thinking in terms of what is being supplied to macro > should not conflict with what is inside the macro? I'm not sure what these two options mean but you should apply `esc()` to any expressions that should be interpreted as referring to things in the calling environment. Not sure if that helps.
