We'd welcome a patch. How to do so is written up in detail at
http://www.sagemath.org/doc/developer/walk_through.html#creating-a-change
. Essentially, you create the change, uploaded it to trac, someone
referees it, and then it gets merged into the next release.

Hi,
Sage uses a dictionary to translate Sage function names to SymPy ones
when they are different.
Signal function is called "sgn" in Sage and "sign" in Sympy but the
respective translation is not in the dictionary, and a error is issued
if one tries to do something like:
x = var('x'); sgn(x)._
