Whitespace delimiters suck

That's not what people are complaining about.  C uses whitespace as a token 
delimter.  It's needed when leaving it out would result in an ambigious parse, 
and if you use it, any arbitrary contigious string of whitespace characters 
makes up a single delimter.  There is never any time (outside of a quoted 
string) when substituting any non-null combination of spaces, tabs, and newlines 
with any other non-null combination of spaces, tabs, and newlines will alter the 
meaning of a program.

That's a far cry from confusion about how many spaces a tab is equal to leading 
to syntacticaly correct but semanticaly incorrect programs.

Even SQL, which has to be the most wart-infested language syntax I've ever seen, 
gets this right :-)
