Forth isn't super practical in such an environment; gForth in particular is a bit "large". (Not that this is bad, but it's of the second school the article mentions.) If you wanted, you could cobble together a Forth implementation that played nicely with pipes. I did this, it works fine, but it's not the type of environment that matches Forth very well.

Forth's design is to give you the machine and let you compute with it rather than to act as part of a pipeline.
