sql-de-lite API seem more schemely to you?
sqlite3 is more OO-like and has many operations which are purely invoked
for their side-effects (returning #void), whereas sql-de-lite seems
more FP-like and
Hello,
I finally got around to touch the code of the SQLite3 egg again: To
make it compatible with CHICKEN 4 I created a version without a
dependency on TinyCLOS, replacing classes with record types and
multimethods with regular procedures. I also wrapped the code in a
module and removed the

depending on your definition of proper, the answer is probably yes

even if the calls don't occur in parallel, invoking the CHICKEN
interpreter from different threads is problematic, since distinct

the problem is that eval never sees local bindings introduced with let
or through function arguments, it always resolves symbols relative to
a top level environment. You should look into the environments egg
