Hello,
I'm having some trouble with a macro using \processaction inside a

Like many of the more complex commands, \processaction does not

becareful at the spaces at the end, ie
\getparameters[Shape][square={unitsquare},

doesn't work.
That's logical, because \Shapesquare eats the spaces following it. In
my case, I define my macros like
\getparameters[Shape:]
[square=unitsquare,
