Unfortunately, they aren't in sequential order in the ASCII table, so
it's not as simple as determining if char c is numeric:
if ( c > '0' && c < '9' ) // c is numeric
Therefore, it's useful for searching quickly, without getting into the
potential mess that could be a regular expression search. Well, I'm
sure for a lot of people it'd be shorter and more concise, but my
relative ineptitude with regular expressions would make it far more
bothersome for me. Am I here to write a language, or to teach myself
regular expressions?
Perhaps it's offtopic in a D forum, but you should use the class
NSCharacterSet for that if you want to be efficient. There's a couple
of methods in NSString accepting NSCharacterSet too which you may be
interested in if you're writing a parser.
