Re: [TCLCORE] TIP #292: Allow Unquoted Strings in Expressions

[Will D. <wi...@wj...>]

Larry,

I can honestly say that in my 20 years as a C programmer I've been
bitten by saying "=" where I meant "==" or "==" where I meant "="
at least a few times every year.  I believe I always caught the error
in unit testing...but it usually left me scratching my head for a few
minutes, because the actual error was so hard to see.

I'd certainly be willing to live with "=" in [expr]; but on the
other hand, using ":=" for assignment in [expr] is cheap-enough
insurance.  I don't really care either way.
