Proposal #9 Status: Variable Name Conflicts
In response to: DCP@TENEX.SCRC.Symbolics.COM
I think PROGV should be removed from the list of forms that check for
variable name conflicts. I think variable name conflicts should be
detected by the compiler; not the runtime system. I think the semantics
of PROGV are that the LAST symbol/value pair takes presedence in case
there is more than one pair for a given symbol.
As I said in response to this question earlier, nobody is proposing a
"list of forms that CHECK FOR variable name conflicts". There is a
proposal for forms in which the use of duplicate variable names "is an
error". Not the same thing.
