I played with SAIL a little on the DEC-20's here, and I have the
manual for it.  The extensions to a very algol-like language include:
	an enormous macro facility (compared to cpp)
	in-line assembly, if you want to risk it
	new data types ITEM and an associative store of ordered
	 triples of ITEMs.  There is a FOREACH statement and a
	 function type MATCHING to search the associative store
	 for triples satisfying certain conditions.

Does MAINSAIL have the latter feature?  I don't know.
