mplib: identifiers starting with units

mplib: identifiers starting with units

[Leah Neukirchen]

Hi,

I've been trying to use the 'cmarrows' metapost library with ConTeXt/mplib.
Essentially it's a thin wrapper around the cmr metafont sources to get
the arrowheads.
This triggers an incompatibility between mplib and classic mpost/mf:

pt#:=1pt;

In MetaFont/MetaPost pt# is an allowed identifier, but in mplib this
results in a parse error.  Unfortunately, pt# is used all over the cmr
sources... would it make sense to allow using this again?

won't change .. maybe you have to define # somehow? or replace that one 
in the mf source
