Hi,
I am a very newbie to Euphoria - I tried it since I need free data =
structure in my project. Euphoria succeeded! I've written working Code =
Generator Genarator within a day.


My questions:

1. Conditional expressions are fully evaluated. Is it an Euphoria bug?=20
I never use this language "feature". I know that it is optional in =
Borland Pascal/Delphi and in Java but I prefer (and don't know anybody =
who don't) shortcut evaluation. It's faster and more usable. For example =
if you run this in Euphoria:

if integer(x) and x<0 then
  -- ...
end if

where x can be of any type (object), you probably end with RTE. Shortcut =
evaluation can be substituted, in Euphoria, only with nested if - it's =
inefficient and annoying.

2. Is there any possibility to change value of non-global variable (e.g. =
an argument) inside function/procedure?


Euphoria language extension suggestions:

1. If answer for Q2 is "No" make it possible - in/out arguments.
in - argument is an input (default)
out - argument is an output
in out - both as input and output

2. Structured gotos (as in Java) and exceptions implementation.

3. "dot" operator. For example:
const
  fX =3D 1,
  fY =3D 2
sequence p
p.fX =3D 0 -- means p[fX] =3D 0
p.fY =3D 0 -- means p[fY] =3D 0
-- It makes code more readable.

4. All preprocessor's (pp) extensions.
