The more I read, the more likely I think this is a bug. For example, the note
following the example in P6E (emphasis mine):
.local string hello
hello="Polly want a cracker?\n"
print hello
.sub _main
hello="Hello, Polly\n"
print hello
end
.end
The first line of this example, the .local directive defines
a *file global variable* named hello. The main routine uses
the same variable, and would give a parse error if it hadn't
been defined. "Polly want a cracker" is never assigned to the
variable and printed.
This just screams bug.
Aside from that, I think .local should be my mechanism to create lexically scoped
names at this level anyway (they serve a different purpose than scratchpads, globals,
etc...).

The scratchpads are a good idea, but clumsy for what I wanted to do here.
