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

Hi,

Heiko: And what about packages, macros that are not released? Documents are allowed to contain macro definitions. Thus existing documents can break because of added new primitives[...]

Nope, since macros defined in the document will always override the primitive meaning. The document will NOT crash and won't need a primitive meaning of the clashed command, since was prepared before the command was implemented. Documents could break if some syntax would change but I belive it will never happen. I can't imagine a situation, where some old document crashes because of a new primitive redefined in the document.
