I've been using it for quite some time and I'm not aware of any
problems.  Command line syntax is usually such that an "=" does
something approximately like what you expect it to.

The only slight oddity I know is that it does "=" substitution as well
as "~" substitution:

% echo animal==cat

but none of the places I know about where "==" is significant occur in
arguments like that.
