TXL has been around for 20+ years now, it's interesting but just never going to be used in production :)

It seems to be meant for research and development, not as the asteroid from the lex manpage. It would make sense as a teaching language for compilers, too. The people who need to know how Lex and Yacc work could read the Dragon Book later.

I wonder if Alan Kay and the Viewpoints mob knew about this, and if so, why they bothered with O-Meta?

It has been used successfully in production. According to this webpage http://www.infoq.com/articles/dsl-interaction-txl it was used for Y2K analysis and conversions of over 3.5 billion lines at IBM Global Services.

Automagical is an Objective-C to C# source code transformation system that uses TXL under the hood.
