Any reason why? In my search of VTK and ParaView, there are lots of
places which use statements like:

    if (${path} STREQUAL "string")

which would work just fine after killing implicit dereferences as well
and fights the principle of least surprise if ${path} is the name of a
variable. By far, the most popular implicit dereference intentional use
is "if (varname)" which is why I'd let that one go.
