System Control Language (SCL), the "JCL" for ICL's VME 2900 OS allowed a
'keyword' to be specified for each formal parameter, alongside its
identifier in the formal parameter list.

The keyword was used in calls and the identifier in the body.  If no keyword
was given explicitly, the identifier was used by default.

This worked well, in my view.
