Re: Allowing '-' in identifiers: what's the motivation?

[Austin Hastings <Austin_Hastings@Yahoo.com>]

At a minimum, there are more multi-word identifiers than there are 
statements involving subtraction. Further, '-' is basic, while all of 
[_A-Z] are not.
Ergo, a multi-word-identifier is easier to type than a 
multi_word_identifier or a multiWordIdentifier.
The older I get, the more I like Cobol, and now *ML, for getting this 
stuff right.
