Hi,

I've taken 2.9 on a ride with my active code bases, guile-log,
guile-syntax-parse and python-on -guile.

Generelly it's a pleasure as always to work with guile. I can compile all
code and especially the
clpfd code in the prolog part works out nicely (A huge file that takes now
6minutes to compile
a 10MB go file).

What's was surprising was that guile-syntax-parse code is much much quicker
than before. Especially the compilation of the racket match.scm file has
improved quite a lot. Prolog code
compiles more quick as well which is very much appriciated.

A few hickups.

1. compiling with O0 fails for me because guile does not translate all
letrec forms down to lover level forms.

2. If you put a lambda as a syntax value and try to execute that code you
get an unhelpful message down in the compiler tower, (types.scm).

Else super work and thanks!
