   I was talking about MPL because that is the only one I have studied
at the moment.  What is the difference between the two outside of the
obvious runtime/compile-time difference?  I was trying to figure out
how a particular placeholder gets its arguments to choose from when
deciding the argument (argument 1 for _1 etc.).
Thank you.
