yes, understandable. I really want named variables, I think we don't
need local variables if we can give the variable better names.
something like
set myvar = whatever
to set it and
${var:myvar}
to expand it. (I don't think we need to set variables in routers.)
but we still need to be able to specify the lifetime of the variable.
coding an explicit clear of the variable's contents when Exim starts
processing the next delivery is awkward and error prone. one solution
is to make "message local" the default and add an extra command and
expansion operator for the "connection local". another solution is to
require variables to be declared before use, with the declaration
specifying the variable's scope.
