[NTG-pdftex] Extensions: \pdf$foo or \$foo?

i've asked several everyday-TeX-users (but quite new to pdfTeX) what 
they think about prefixes. \pdf* prefix for commands not related to PDF 
are *more* confusing than non-prefixed that may occasionally conflict 
with macros.

IMHO much better than \pdfmatch. However, in 2010 nobody will remember 
that regex support was an extension in 2005. All prefixes encounter this 
problem. Thus, I agree with Taco, that if some command can't be grep-ed 
in representative TeX archives, it can be used as a new primitive.
