Aside from code-breaking issues, I just don't go for:

   a.push!(123)

nor for the idea that:

   a.push(123)

doesn't push 123 onto a.

push! is redundant, because ! is just one way (and, in Ruby, not
even fully that, as documented) to indicate that a receiver is
being changed.  Some methods already have names that unambiguously
indicate such change (push, delete, etc.).  Unambiguousness 
obviously entails knowing what such things mean in the first place,
but that's true of ! and everything else too.

I know that the binary logic of !/not ! (or !/!! :-) has a certain
symmetry to it, but I don't think that symmetry maps at all
comfortably, at least in a universal way, onto the semantics of
Ruby method-naming.
