The Tangler is one of the cleanest components of FunnelWeb, as basically all it has to do is expand some very well-defined macros.
Text indentation: Currently FunnelWeb supports ıno indentation and ıblank indentation. A third form could be added if it was considered necessary. ıText indentation is the same as ıblank indentation except that instead of indenting with blanks, FunnelWeb would indent with the text to the left of the called macro. This facility could be useful for commenting out large bodies of text in languages that do not have multi-line comments (e.g. Ada). A discussion of the pros and cons of this form of indentation appears earlier.textindentation
