Less DWIM, please.

Arrays aren't uninitialized. They contain zero or more scalars, some of
which may be uninitialized.

Yes! I think of the quotes as:
' - for strings not doing any variable interpolation
" - for strings doing interpolation, or including digraphs
I have often wished that digraphs were not bundled with variables in this
respect, i.e., I wanted to put a string containing \n inside single quotes
just 'cuz it didn't contain variables to be interpolated. Whether there's
a way of improving this behavior or not I don't know.
