I was thinking more of larger macros like CHAR_TABLE_REF_ASCII,
where it can be helpful to step through the interior loop.
This cannot be done easily right now -- I typically drop into
machine code, which is painful.

Even for XINT, it can be helpful (for a beginner, anyway) to step
through a function, for example, to see what happens with integers
that are out of range for Emacs fixnums.  I know that Emacs has
gdb macros that substitute for straightforward commands to print
expressions, and these are useful for the long-time Emacs experts who
know about them, but it'd be nicer if debugging also worked in the
usual way without requiring this additional expertise.
