coding style

[Donn Cave <donn@u.washington.edu>]

Is anyone willing to step forth with ideas about how es code could look?
Obviously, what works is the first criterion, but there seems to be a
kind of a Lisping quality to es that benefits a lot from clear indenting,
and possibly some logical operations that I don't see yet.

for example, the following rc

	if (~ $TERM () || ~ $TERM '') {
		TERM = unknown
	} else if (~ $TERM *' '*) {
		t = () {
			eval 't = (' $TERM ')'
			TERM = $t(1)^-^$t(2)
		}
	} else if (~ $TERM *vt520) {
		TERM = vt52
	}

translates to es?

	%or	{%and {~ $TERM () || ~ $TERM ''} {TERM = unknown}}
		{%and {~ $TERM *' '*} {
			let (t = ()) {
				eval 't = (' $TERM ')'
				TERM = $t(1)^-^$t(2)
			}
		}}
		{%and {~ $TERM *vt520} {$TERM = vt52}}

(we were having problems with flaky TERM values, obviously)
I'm not proposing the above, I'm exposing my ineptitude in the hope that
someone will be inspired to improve on it.
