In Hermes, which actually does this sort of constraint propagation, you
don't have the ability[1] to munge some other routine's[2] local
variables, so that becomes a non-issue. You wind up with some strange
constructs, tho, like an assignment statement that copies and a
different assignment statement that puts the rvalue into the variable on
the left while simultaneously destroying whatever variable held the rvalue.
[1] You do. Just not in a way visible to the programmer. The compiler
manages to optimize out most places that different names consistantly
refer to the same value.
[2] There aren't subroutines. Just processes, with their own address
space, to which you send and receive messages.
