Succeed to run guile-bash on Guile 3.0.5

[Oleg Pykhalov]

Hello,

I succeed to run guile-bash on Guile 3.0.5.

First of all, when you point "guile" input to "guile-3.0-latest", you
will have the following output:

So, as a temporal workaround I just coppied those files, but without
‘.go’.  We cannot use compiled ‘.go’ Guile files, because we will get a
not helpful error message in case we use ‘define-bash-function’:
