It depends on what you find "convenient".  For any macro, I have to
remember which arguments are evaluated and which not, or read the docs
every time I want to use it.  Macros make debugging harder.  Etc.
That's why we usually avoid macros when a function would do.

I understand that you find your suggestion more convenient, but OTOH it
would not be consistent with similar functions we have and introduce
another inconsistency.  I just think it's not worth it.


Michael.
