The QsciLexer classes are simply containers for the configuration of the
corresponding underlying Scintilla lexers.

The Scintilla lexers are designed to recognise different language elements
so that they can be rendered differently (different colours, fonts etc.). A
typical lexer has no understanding of the overall structure of the
document.

You probably want to look at how Scintilla/QScintilla implements call tips
and auto-completion.
