How am I supposed to write a vardef with `@#' in context?
For instance, the following
\startuseMPgraphic{annot}
vardef annot@#(suffix n)% noeud
(expr l)% étiquette
(expr a)% angle
=
label@#(l,n.c+(cosd a,sind a)*labdist);
enddef;
\stopuseMPgraphic
produces the error:
! Illegal parameter number in definition of \MP:annot.
<to be read again>
(
<argument> vardef annot@##(
suffix n)(expr l)(expr a)= label@##(l,n.c+(cosd ...
\dostartuseMPgraphic ...leuseMPgraphic {#1}{#2}{#3
}}
l.54 \stopuseMPgraphic
Thanks,
Denis

# symbols are always nasty for tex since there are some low level hard
coded things going on which makes it nearly impossible to catch them,
\appendtoks \let\#\hashletter \to \everyMPgraphic
\startuseMPgraphic{annot}
vardef annot@\#(suffix n)% noeud
(expr l)% tiquette
(expr a)% angle
=
label@\#(l,n.c+(cosd a,sind a)*labdist);
enddef;
\stopuseMPgraphic
Mea Culpa,
Hans
