Apart from checking plain.mp and the MP manual, the way to find out whether something can be implemented or not is to refer to "The METAFONTbook", particularly the two chapters on macros (definitions), i.e., 18 and 20.  "MetaPost:  A User's Manual" probably doesn't provide enough information.

There is no particular difficulty in defining a macro using `def' or `vardef' to insert text, but I don't know if it's possible to get the exact syntax you want.  I haven't read through Taco's solution.
