90% of complaints is better!

The existing bind placeholders do not overload any operators. bind(...)
== bind(...) is a valid bind expression though, iirc. Well I've used it,
so it better be :-)

Maybe another solution is to deprecate all the other bind/placeholder
libs and suggest using Phoenix bind. That is, there is no point using
any of the other libs besides "The Chosen Lib." Not sure that will work
out too well though.
