On the one hand, factor -does- have named variables.
On the other hand, once you start experimenting with stack stuff there's a moment where you go "aha" and it actually starts to make a lot of sense for temporary variables.
There are probably other aha moments further in that I haven't got to yet; I've not spent as much time with factor as I want to.
I dunno if I'll ever use it for "real stuff", but I think it's worth fighting your way through to the aha moments just like lisp and haskell are even if you never expect to use -them- for "real stuff".
