 -- A miniature stand-in for the Scintillua lexer module, just enough for the
 -- syntax-highlight checks to drive every path through the filter without the
--- real collection installed. load() hands out one of the toy lexers below by
--- name and detect() recognises a single filename suffix or a shebang naming

--- load or one that raises while lexing, has a name here too.
+-- real collection installed. detect() names a lexer after the filename's
