4.6: adda/cstr/declare block/
complication of being implicit:
. the problem with not needing a
special symbol for declare block,
is that if I happen to be in a parenthetical
but I was declaring a var meant to belong to the enclosing body,
then under the current system,
the fact that I've made a var declaration in a parenthetical
has converted that a declare .
. the way out of this is to use a path name
to show where the declaration is being made:
( ../belongsToEnvirons.t; ).
. there was also the idea of typing the parenthetical
in order to declare it to be a namespace,
so then untyped parentheticals would not be
deallocating what was declared within them .
