until

Until!(pred,  Range,  Sentinel) until(alias  pred =  "a == b",  Range,  Sentinel)(Range range,  Sentinel sentinel,  OpenRight openRight =  Yes.openRight) if (!is(Sentinel ==  OpenRight))

Lazily iterates range _until the element e for which pred(e, sentinel) is true.

This is similar to takeWhile in other languages.

Parameters

`pred`	Predicate to determine when to stop.
`range`	The input range to iterate over.
`sentinel`	The element to stop at.
`openRight`	Determines whether the element for which the given predicate is true should be included in the resulting range (`No.openRight`), or not (`Yes.openRight`).

Returns

An input range that

iterates over the original range's elements, but ends when the specified predicate becomes true. If the original range is a

forward range or

higher, this range will be a forward range.

fnUntil!(pred, Range, void) until(alias pred, Range)(Range range, OpenRight openRight = Yes.openRight)
