Huh. This is very interesting.

One thing that springs to mind is that some parts of assembly
languages behave like this, using registers to hold arguments:

MOVE x <- a
MOVE y <- b
MOVE z <- c
CALL foo

..where the first three lines can be permuted any which way. 
In an even purer version of this idea, expressions might not be
allowed on the right side of assignments (another `order matters'
`anonymous temp value' kind of technique) so instead of

MOVE x <- y + bar(1)

you would need to write

MOVE barIn <- 1
CALL bar 
MOVE +In1 <- y
MOVE +In2 <- barOut
CALL +
MOVE x <- +Out
