Enclose with double quotes in the terminal does nothing:
myapp --modelicalibs "file-a.mo" "file-b.mo"
will give you EXACTLY the same string args as:
myapp --modelicalibs file-a.mo file-b.mo
I think Jon's point is that it's difficult to distinguish where an array
list ends if you get the parameters as separate items.
myapp --numbers 1 2 3 -5 -6
Is that numbers=> [1, 2, 3, -5, -6]
or is it numbers=> [1, 2, 3], 5 => true, 6 => true
This is probably why the code doesn't support that.
