I find this great, finally an easy way to play with ALGOL 68, beyond the few systems that made use of it, like the UK Navy project at the time.
Ironically, Algol 68 and Modula-2 are getting more contributions than Go, on GCC frontends, which seems stuck in version 1.18, in a situation similar to gcj.
This makes me worry for the GCC implementation of Rust. People do not seem to use or upkeep the GCC versions of languages who primary Open Source implementations are elsewhere.
There is the advantage that GCC will be only way for Rust to be available in some targets where LLVM isn't an option.
Regarding Go, gccgo was a way to have a better compiler backend for those that care about optimizations that reference Go compiler isn't capable of, due to the difference in history, philosophy, whatever.
Apparently that effort isn't seen as worthwile by the community.

Either way, today is for Algol's celebration.
