Yes, absolutely. Red has a `parse` function, that uses EBNF-like rules, but someone has written a nice regex translator if you need that bit. It's also possible to write a nice AWK-like dialect that handles things at a higher level. I've done that in the past. One of the current limitations is that the I/O model is simple, and there is no GC yet. Those will come in the relatively near future, but if you have large files, or need long running processes, it will be more work for a while. Still doable, just not as easy.
