In MetaPost 1.002 (Web2C 7.5.5), the help text says,
Usage: mpost [OPTION]... [MPNAME[.mp]] [COMMANDS]
If the first line of MPNAME is %&MEM, and MEM is an existing
.mem file, use it. Else use `NAME.mem', where NAME is the
program invocation name...
Alternatively, if the first non-option argument begins with
a &, the next word is taken as the MEM to read, overriding
-mem=MEMNAME use MEMNAME instead of program name or a %&MEM
but %&MEM line overrides that
and -mem=MEMNAME or &MEMNAME on command line overrides that.
I do, however, remember the days when plain was the default
for tex and metafont. In emTeX, this persisted through the
late 90s, even in metapost. I don't know if that was ever
the case in web2c.
