Interesting thought...but it's not going to scan it *again*, so unless
you're worried about the SIGNAL getting triggered before the first
non-quoted function call (and what are the odds of that?) it's not really a
very interesting case, I don't think. Unless, as noted earlier, you're
insane enough to override a BIF.

I got bitten by this a long time ago (no, I did not override any BIF). 
The exact circumstances I don't remember but it was cured by quoting the BIF functions.
