Dear all,
Why C and some of other languages dont allow the name of a variable
start with a digit?
It's been explained there could be ambiguity between integer constants and
variables.
It might have been feasible where there was no ambiguity (so 0XABC must be a
constant, but 0XABG must an identifier), but it's unsatisfactory. Some other
way of distinguishing constants and identifiers would be needed, and this
would offset some advantage of starting with a digit.
More useful (to me anyway) would have been the ability to use $ in an
identifier (available on some Cs but not standard). Then it could have been
used in place of _, which is difficult to see and can be confused with __
and ___.
