" Debugging:
" If you'd like to try the built-in debugging commands...
" :MatchDebug to activate debugging for the current buffer
" This saves the values of several key script variables as buffer-local
" variables. See the MatchDebug() function, below, for details.
" TODO: I should think about multi-line patterns for b:match_words.
" This would require an option: how many lines to scan (default 1).
" This would be useful for Python, maybe also for *ML.
" TODO: Maybe I should add a menu so that people will actually use some of
" the features that I have implemented.
" TODO: Eliminate the MultiMatch function. Add yet another argument to
" Match_wrapper() instead.
" TODO: Allow :let b:match_words = '\(\(foo\)\(bar\)\):\3\2:end\1'
" TODO: Make backrefs safer by using '\V' (very no-magic).
" TODO: Add a level of indirection, so that custom % scripts can use my
" work but extend it.
" allow user to prevent loading
" and prevent duplicate loading
