Thanks, I must have missed it.  Sorry about that.

Yeah, 7.2 now.

That code is bogus too, but I didn't want to burden you with this, at
least not for this patch ;).

Totally understood.  This is all my fault or Thiago's :)

Yes, I think we should change it so that "print foo" or "str(foo)"
yields the "most natural" name.

In this case it is just the print name.

Yeah, sorry, do like sympy_str.  In this case I think it should just
return the filename.

Phil> Ditto, sympy_str comment.

I am not sure what is nicest to return here; it is probably fine to
leave it as-is for the time being.

thanks,
Tom
