Maybe something like:
#keyword gradient2(Vect)
    // any pattern stuff...function {}, pigment_pattern, etc...
#end

This would add a new keyword with the "keyword keywordParameters" 
syntax. You would then use "gradient2 GradienVector" to use the pattern. 
Or maybe something like:
#block_macro MacroName(Parameters)
#end
This macro would be called like:
MacroName {Parameters}
instead of the usual parenthesis call.

I've done something similar with a function include file that has 
functions for most of the patterns. Most of the functions are just 
pigment functions, but a few are implemented directly.
