I doubt languages without /map/ are up to the job.
Great, why don't you continue to use lisp then? If pascal does not
offers the language concepts you are used to, pascal is the wrong
language for you.

No need to wait, checkout the fixes_2_6 branch, which is currently at
version 2.5.1, but will become the v2.6.0 release. This also means you
will help test the future 2.6.0 release and catch any possible bugs

I'm using the SVN trunk, but it's not working for me for some reason.

Didn't you just say that you're using 2.4.4? Trunk is currently 2.7.1.

IMO, it's because they're lazy to declare things before they use it. Often,
an anonymous function which first used just once eventually used more than

Can't you do the lookup in the DB server by a SQL join for example?
Or, if you need do some processing in between, use 2 queries and build the
where clause for the 2nd from the results of the 1st. If you don't need
the full table, don't use select *.

anonymous functions = closures = lambdas are part of functional

How are Assigned, Free, Nil and Destroy related, and when is one or another
