Range-Foreach Syntax

Reference this package to write foreach-loops like this:

foreach (var index in 0..100)
{
    // loop body...
}

which is equivalent to the legacy for-loop below:

for (int index = 0; index < 100; index++)
{
    // loop body...
}

NOTE: Use ^ to represent negative numbers, e.g. ^100..0 (instead of -100..0).

Stepped Syntax

If STEPPED_RANGE is defined, this syntax can also be used:

foreach (var index in (99..^1).Step(-2))
{
    // loop body...
}

Which is equivalent to the legacy for-loop below:

for (int index = 99; index >= 0; index -= 2)
{
    // loop body...
}
