Thanks.
Exactly. but it would probably be more clear to state that "the name
'$x' in the lexpad is bound to a item container", binding is something
that happens to the variable as stored in the lexpad, so it's an
operation that happens in the lexpad, not in the container...
I think you're agreeing with me. True, by "$x" I meant the symbol as
resolved to a particular scope. "lexpad" is not mentioned in the
synopses. Behaviorally, the symbol table such as MY:: or some package
appears to be a hash that associates the declared name with the container.
(that simplifying the point where the lexpad is also a container)
That I don't follow.
%a<b> := 1;
is an operation in the hash itself, not in that specific cell of the
hash.
What?
Nothing in S02, S03 or S06 suggests such a usage. := is used to alias a
"name" The expression on the left does not name a variable, but is an
expression.
