Preexistent definitions of a sub whose name is handled by L<Sub::Op> are restored at the end of the lexical scope in which the module is used.
But if you define a sub in the scope of action of L<Sub::Op> with a name that is currently being replaced, the new declaration will be obliterated at the scope end.
+Function calls without parenthesis inside an C<eval STRING> in the scope of the pragma won't be replaced.
+I know a few ways of fixing this, but I've not yet decided on which.
