- a syntactic sugar for array_key_exists and property_exists, maybe
called hasitem(); hasitem($foo['bar']) would check $foo has the item
'bar', but hasitem($foo) would be an error
The most important, IMO, is a more intuitive, readable alternative to
array_key_exists(). Checking the existence of a plain var is important
for completeness and should be available, but remains an edge case, and
property_exists() seems sufficient.
Anyway, the problem we have with names like 'exists' or 'hasitem', is
that they would become reserved names. So, they couldn't be used as
function/method names anymore, creating an important BC break.

What about the context sensitive lexer ? exists() would be reserved as a
function name, but not more than that.
