The compiler recognizes the situation and reports it as an error, so it seems like this is not a bug, but something which is not supported: ~/scratch $ rdmd test_scope_a.d test_scope_a.d(6): Error: declaration f0 is already defined in another scope in main The rationale in TDPL that Andrei pointed to doesn't seem to cover the case above.

I think it is a bug. Technically I understand it - Walter names inner functions like main.f0, which does not leave room for functions with the same name inside the same function. Shouldn't be difficult to fix though. Mind submitting a bug report please? Andrei
