Actually changing in (language python compile),

(define (letec f)
  (let/ec x (f x)))) 


(define-syntax-rule (letec f)
  (let/ec x (f x)))) 

Actually lead to similar speeds as python3.

Pro tip, when running this on guile the scheme code that it compilse to is located in log.txt.
If you ,opt the resulting code in a guile session you might be able to pinpoint issues that 
delays the code execution.

(I should perhaps add that my script doesn't benchmark the object system but rather loops, conditionals and integer arithmetic.)

Yesterday, Andy committed new code to the compiler, some of which concerned skipping some arity checking.

Also, Stefan meanwhile committed something called "reworked object system" to his python-on-guile.

Sorry for coming with unspecific information (don't have time to track down the details) but I noticed that my benchmark script written in Python, and which computes the 20:th Ramanujan number, now runs 60% faster than before these changes.

This means that python-on-guile running on guile3 master executes python code only 2.6 times slower than the CPython python3 interpreter itself. :-)

Have a nice weekend all,
