Macro factory and argument passed at calling (part 2)

I am making a factory macro (A) that produces another macro (B). Macro B consists in affecting what it gets as parameters to variables when called. I am currently able to do all this without A, but this is not scalable, because it requires a lot of rewritting.

See Macro factory and argument passed at calling for the whole context.

Following the answers on question the previous question (Macro factory and argument passed at calling ) , I could make a new MWE with some points still opened :

• point 1 : I put comas in the \clist_map_inline to artificially delimit each argument
• point 2 : I put the list of the argument in the definition (the 3 m) : \NewDocumentCommand{\DefinitionVariables}{ m m m }%
• point 3 : I put all the arguments in the \clist_map_inline function : \clist_map_inline:nn { #1, #2, #3}%

So the questions following these changes are :

• point 1 : How can I, not have to put a comas ? I guess it has to do with the \clist_map_inline function, with coma being a built-in delimiter. It raises an issue when there is a coma inside an argument as the function will cut it as it considers it's a delimiter. I was thinking of having kind of a \foreach argument in {all the arguments}. Does such a thing exist ?
• point 2 : How can I make this m dynamic ? By dynamic, I mean : sometimes, the function can take 3 arguments, but sometimes it can be 7 or 9 (between 1 and 9). Something like numberOfArgument * m

• point 3 : It's related to the previous point, how can I also make this dynamic and not hard-coded ? (the \foreach argument in {all the arguments} would solve it).

Any help is very appreciate !
