Because GF doesn't parse the complete symbol because it needs to do it 
real fast as it has to continually do it for every symbol that comes into 
any inlet of GF. When I have a list like (1 2 3) then "(1" is a symbol and 
"3)" is a symbol. But when doing things like that, open-parens only happen 
at the beginning of a symbol and close-parens only happen at the end. In 
your case, one of the spaces is a real space inside of a symbol, therefore 
the "(" is not recognised as opening, but the ")" is before a separating 
space, and thus it counts.

because Pd's syntax is insufficiently developed. I used to be able to 
write {1 2 3} and the software's parser would parse it as an element of 
type 'list'. Then I had to switch to Pd and had to add weird hacks to keep 
on supporting such a thing.
