Description:
If I correctly understand how the parser works, parameters for parser functions
are parsed _before_ they are passed to parser function hooks. This seems awfully
wasteful, especially for #switch and different flavours of #if, where big chunks
of code, including metatemplates, are often parsed and thrown away.

Parsing could be left up to the hook functions to do as needed, preferably with
a new way to set such hooks, so that the current extensions don't get broken.
