Comment(by burcin):
Replying to [comment:3 vbraun]:
> 3) I think removing the underscores from other `is_something()` is in
the spirit of this ticket of exposing more introspection capabilities to
the user. I don't think there is any argument to be made that the user
must not be able to access these functions. Rather, it adds obvious
functionality to the public API.
I agree that these functions should be exposed to the user. I was the one
to add them with an underscore in the first place, with the thought that
they are only useful if you want to get into the internals of symbolic
expressions. But anybody who wants to do any serious programming with
symbolics needs them. They should be more visible.
I also appreciate any effort to clean up the public API of symbolic
expressions. This has been a mess for a long time. AFAIK, it was written
to expose some basic maxima functionality initially, then somehow it was
decided to keep this old interface and not use the (much better designed)
ginac one.
