The "constrained environment" is the rub. In the old days, supporting a time sharing dev environment for 30 users (with 2K dedicated memory each), or getting to a functional self-hosted prompt before the floppy drive spun up to full speed, or fitting a dev environment in a single jumbo packet, etc. were not only cool, but were technically required.

We have megahertz and gigabytes and "embedded" systems with MMUs and filesystems at our disposal, so I'm guessing the time when forth was a solution has long since past.
