+ *b:match_function*
+If b:match_function is defined, matchit.vim will first call this function to
+perform matching. This is useful for languages with an indentation-based block
+structure (such as Python) or other complex matching requirements that cannot
+be expressed with regular expression patterns.
+
+The function should accept one argument:
+ forward - 1 for forward search (% command)
+ 0 for backward search (g% command)
+
+The function should return a list with one of these values:
+ [line, col] - Match found at the specified position
+ [] - No match found; fall through to regular matching
+ (|b:match_words|, matchpairs, etc.)
+
+The cursor position is not changed by the function; matchit handles cursor
+movement based on the returned position.
+
+If the function throws an error, matchit gives up and doesn't continue.
+Enable |b:match_debug| to see error messages from custom match functions.

+Python example (simplified): >
+ let s:keywords = {'if': 'elif\|else', 'elif': 'elif\|else'}
