Can you explain this? The way I see this, the piece of code that does
the actual aliasing is yours, and this piece of code is unaffected by
aliasing alias_method or any other dirty trick, so a check in that
piece of code should work perfectly for detecting if eval and consorts
get aliased. Of course, this is a run time check and not a compile
time check, but I think this is what Brent is proposing. Besides,
there is no way you can check this at compile time because aliasing
eval and consorts can be done in any single eval anywhere in the code.

If anything, you can always disallow aliasing alias_method ;-)
