If I made a branch which warned when implicit expansion was done, would folks be willing to run it over various codebases to see how annoying it would be to just remove it altogether?
To be clear, are we talking about in the case of e.g. STREQUAL, or *ever*? Because I'm sure breaking 'if(Pkg_FOUND)' would be very, very bad :-).
I'd be a little suspicious of even the former; I know at least in my case, greater understanding of implicit expansion leads to greater *reliance* on it as a guard against unintended expansion (i.e. 'if (FOO STREQUAL "...")' instead of 'if ("${FOO}" STREQUAL "...")').
(Loosely related: if variable names were sane, it would at least be safe to write e.g. 'if ("#${FOO}" STREQUAL "#...")'. But alas, '#${FOO}' might still be the name of a variable.)
