Well, if we think of it as separate steps, resolving the function 
"length" is what's failing here. The subsequent () would just 
call it, if it existed, but the name of the property/symbol would 
still be "length".

But yes; you could make a case that, in the case of invalid 
function calls, it should include the whole erroneous attempted 
function signature in the error message. I can imagine it 
becoming ambiguous once templates enter the picture however, and 
for not much gain.
