if ? is good then ?? is better

We now have ? for quick and easy display of a object, in its natural numeric format.

It would be handy if ?? could display an object as if it were string data. This could be a kind of pretty_print() without arguments.

sequence test = "try this" 
? test 
-- {116,114,121,32,116,104,105,115} 
?? test 
-- "try this" 

• it would be very convenient for developing programs
• it would make introducing Euphoria to newcomers much easier
• it would make example and tutorial programs simple
  

loop until

The syntax for loop until breaks the Euphoria pattern.

currently:

loop do 
	a = a*2 
	x = x-1 
until x < 0 

Could this be at least allowed as an "alternative" syntax?

loop do 
	a = a*2 
	x = x-1 
until x < 0 end loop 

The "end" keyword is fundamental to current Euphoria syntax. In the documentation we now have to explain (apologize) that this has a "distinctive form."

For example, it is generally clear that scope for a syntax element finishes at the "end" keyword. In "loop do" this no longer applies.

It would be best if the patterns of syntax now in Euphoria are maintained.

I forgot to mention that we almost have this now.

include std/console.e 
 
display("test string") 
display(12.34) 
display(56) 

gives ...

test string 
12.34 
56

Please add the "end loop" (as the only choice) to the Beta. The display() routine means that ideas like ?? can until for the 4.1 release.

loop do 
... 
until X 
end loop 

This construct is very bad at all. The Russian translation of "until" is "do teh por, poka", and "loop" is extra word here. So I'd like:

do 
... 
while X 
end do 

Or just abandon it for ever, please.
But ?? seems to be very nice, I like this idea very much.

We have

while X -- check for condition X **before** doing 
do 
... 
end while 

And we can have

do 
... 
while Y -- check for condition Y **after** doing 
end do 

All depends on conditions X and Y, see?
And we do not need the new "loop" and "until" key words.

Hey, Jim, do you speak Russian?
Then, code has to be translated word-to-word to avoid any confusion.

Tom, your idea about ?? seems to be excellent!
Congrats!

These double messages 10 and 11 seems to be produced by the Reload button pressed in browser on the Thanks page. Is it a bug or feature if so?

I like the "end loop" idea. It is consistent with other ways of ending branching and looping constructs.

Or, are you pressing "Reload" on the "Message posted OK" page? I can see that happening.

I wholeheartedly agree with the "end loop" proposal. When I read for the first time the specs of Euphoria 4.0, I thought I would never use the loop / until construct because of its inconsistent syntax. (Euphoria 4.0 is however a huge improvement: a great thanks to all the developers!)
