While experimenting with code-completion for ECMAScript I noticed a
limitation with array comprehension syntax.
The syntax as proposed (and implemented in Mozilla) has the output
expression before the loop and filter:
[i.toString() for each (i in [1,2,3]) if (i != 2)]
The problem is that the variable i in the output expression is defined
by code to the right of it.
How do you address the following function?
function foo()
{
i = 3;
var i;
return i;
}
Or this one?
function foo()
{
try
{
var i = 2;
throw i;
}
catch (e)
{
return i;
}
}
Name before declaration is a problem already posed by the existing language
syntax, isn't it?
