Re: [Hecl-devel] More problems with lists

It's not lists at all, it's anything that uses setVal from a command.
incr has the same problem:

hecl> proc ic {} { puts [incr 1] }
hecl> ic
2
hecl> ic
3
hecl> ic
4
hecl> ic
5

append, lappend, lset, linsert, incr will all exhibit the same behavior.

That's why I'm contemplating a different method for Thing,
setValIfCopyNotSet (or something nicer, presumably), that only sets a
new value if the copy bit is not set.
