in keyvalmp.mp i've simplified the problem to picture-keys, since the
problem will occur mostly in those cases.
But the problem exists for all given values that contain groups of (...)
where the (...) is not a pair or color.
For example, using MetaFun, even foreground=cmyk(1,0,1,0) does not work.
(BTW, this problem with a list of 4 numerics in a (...) could be solved,
but not if the (...) contains a list of 5 and more numerics)
Therefore i prefer something like:
defineLogo(MyLogo)(
label("some text",origin) ;
) ;
TheKeyValMacro(logo=MyLogo) ;
In contrast to your suggestion, here one can use strings in the picture
expression.
