Hello.

I believe this is a bug, but then again probably it would have been noticed by now..

Anyway, here follows:

Inductive one : Prop := True.

Inductive two : Prop := True.

You won't be able to evaluate the second definition, Coq gives

Error: True already exists.
Sure, you could say that I shouldn't use Inductive in such cases, but still... (I noticed while using this 'Inductive' as a placeholder)
