> Do you mean one would have to always pass the suppress_warning thing?
I'm not completely sure what you mean. I'm going to take a shot and say
only if one wants to suppress the warning, not if they didn't care if it
has a warning or not. For example,
{{{
sage: domain._get_coerce_map_internal(codomain)
}}}
will work because of the default value of `True` (and display the warning
message as well).
@Simon, I don't think that will work because python should run the copy
before passing to the lazy string, since I think the string's formatting
is the only thing being lazily done.
