i ran with some ungrounded assumptions, and i basically explained how it works 
in CL, not in Guile.

sorry about that!

i played a little with your test now.

maybe i'm stating the obvious here, but its behavior is in harmony with the 
hypothesis that the compilation of DEFINE (wrongly) evaluates the value in the 
newly updated environment (as opposed to the "parent" environment, i.e. the one 
before the definition has been added/set).

i briefly tired to find the place where DEFINE is compiled to check this 
hypothesis in the code, but i couldn't find it.
