Which will cause an exception, BTW, since the count method
requires one parameter telling it what you want to count
occurrences of.

He assumed you were because you were trying to call a function
without using parens. VB is probably the most common language
where you call something by writing
functionName
rather than
functionName()
IIRC Pascal precedures are called w/o parens, but if you pick
Joe Random off the 'net he's more likely to know VB than
Pascal.

Do any of them call functions w/o parens?
