Why not have the parameter as:

"--first=11,12"

instead of trying to create more than one parameter with the same 
parameter name.

Personally because of the type of solution I suggested, which is 
probably the way most uses of such a multi-value value parameter would 
look like, with possibly a different separator than a comma, I do not 
think a parameter library should have to cater to the same parameter 
name more than once on the command line.
