I have been bitten by this problem many times as well.

This is one of the things I wanted to start looking at for 8.5.
My idea was to optionally use : or @ (not sure which is more popular) to
specify this token is only a variable. Do not try to match it to columns or
other database object. If the variable did not start with : or @ then normal
rules would apply for backwards compatibility.
No idea how feasible this plan is, I was just hoping to find a way to solve this
problem.
Thanks,
