!? the ability to pass typed records around is an idea that was
tarred, feathered, drawn and quartered by unix. files, and therefore
streams, have no type. they are byte streams.
one of the advantages of unix over, say, ibm systems, is that in unix
it is not the os' business to care what you're passing about. but by
the same token, if you are the application, you get to arrange these
things by yourself.
rc already passes structured data through the environment.
rc variables in the environment are defined as
var: [^ctl-a]*
| ([^ctl-a]*) ctl-a list
so there is precident for this in shells.
