Heh?

I use length({}) all the time, and never had it crash
on me.
I use it frequently in a language library to see if an
include file wich has being parsed doesn't contain any
code.

BTW, that reminds me, if anyone wants this
'language.e'
library, tell me and I will post it to the list.
It's perfect for creating programming languages, as
the boring and tedious crap like parsing and getting
include files is allready done for you.

I made it cos I got sick of rewriting a damned parser
in every language tool I wrote, and try to reinvent an
include file system.
For example, the first time I wrote a language tool, I
was breaking my head over how to write an include file
system.
Yeah I know, it sounds easy at first glance, but
consider a file called a.ex wich includes l.e, wich
inturn includes d.e and c.e, wich all include o.e,
etc.

So anyways, anyone needing this small library,
especially suited for implementing Euphoria
translators and interpreters, ask and I will post it
to the list.
