I agree, but the UBoard has some advantages: different topics can be
discussed in separate threads, all the posts are easily accessible
for everyone to read, and voting about a topic can be made easy via
the polling functionality UBoard offers.

You're right about that one. These abbreviations don't bother me, because
everybody uses them. And 'positive_int' wouldn't bother me if the integer-
type would be called 'int' in Euphoria. I just think it's a good idea to
have consistent naming conventions.

Here are some more suggestions I have for ESL:
- the constants TRUE and FALSE
- bitwise functions
- a mechanism to ignore return-values of functions. Some options:
  -> a global variable VOID: VOID = functionToIgnore(...) (like Win32Lib)
-> a procedure ignore that does nothing: ignore(functionToIgnore()) (like
  Win4Eu)
- an enumeration-mechanism: here's how it was done in Win4Eu:
 

constant DAY_OF_WEEK = enum()
  constant MONDAY = next(DAY_OF_WEEK),
           TUESDAY = next(DAY_OF_WEEK),
           WEDNESDAY = next(DAY_OF_WEEK),
           THURSDAY = next(DAY_OF_WEEK),
           FRIDAY = next(DAY_OF_WEEK),
           SATURDAY = next(DAY_OF_WEEK),
           SUNDAY = next(DAY_OF_WEEK)
  

- advanced C/API-interface functionality (WIN32/LINUX)
