Comment (by nbruin):
Replying to [comment:3 nbruin]:
> {{{
> sage: preparse('f(u,v)=u+v')
> '__tmp__=var("u,v"); f = symbolic_expression(u+v).function(u,v);
"Defining f and u,v"'
> }}}
would provide another flavour. Here, essentially the warning is the
"value" of the assignment, so it only gets printed if values of statements
do (i.e., in interactive environments).
If you want to get rid of the quotes in printing:
{{{
class NonQuoteRepr(str):
def __repr__(a):
return a
}}}
and return
{{{
NonQuoteRepr("Defining f and u,v")
}}}
instead. Perhaps we already have a class for representing messages that
does this.
