Loop iterator - example.txt

[Rick C. Hodgin]

Here's an idea:

There should be a way in D to allow the reconsideration of a for..loop test
clause without executing the increment clause.

Using the terminology:
for (initialize-clause; conditional-clause; increment-clause)

Example:
int i;
for (i=0; i<10; i++)
{
if (string.substr(i,1) == something)
{
i += some_other_function();
retry;
}
else if (string.substr(i,1) == something_else)
{
i += some_other_function2();
retry;
}
// Otherwise, simply execute the "i++" and re-test
}

I propose the name "retry" for the "retest without increment-clause" command, to
be used in a manner similar syntax-wise to the way "break" is used today.
"Retry" would simply bypass the increment-clause and proceed straight to the
conditional-clause code section, thereby allowing subsequent passes through the
for loop without the requisite and occasionally unnecessary auto-incrementation.

It would just be a way to give for loops a little more natural utility without
having to do some rather obtuse programming techniques, such as using goto's or
enclosing the code in a while or do loop, etc.
