Hyperlambda loops

Loops in programming languages implies doing something x number of times, where x is any number. Hyperlambda provides two basic slots for looping; [for-each] and [while]. Notice, there is no “for” loop in Hyperlambda, since this can always be created using the [while] loop. The [map] slot also iterates a node-set, but collects the result of each iteration into a new result set.

for-each - [for-each] iterates through each node being the result of an expression, and evaluates its lambda object, passing in the currently iterated node as a [.dp] argument, containing the node currently iter
map - [map] iterates through each node being the result of its expression, the same way [for-each] does, and evaluates its lambda object once for each node, passing in the currently iterated node as a [.dp]
while - Semantically similar to [if], but instead of evaluating its lambda object once, will iterate it for as long as the condition evaluates to true.
