Class Loop

public class Loop

extends Object

Safe: An StaticMaker on this class is the function named "__loop" in the universalScope (and therefore also in the safeScope).

This wrapper is used as the E language's primitive looping construct. When called as a one-argument function, it just repeatedly calls its argument as a zero-argument, bool-returning function until that function returns 'false'.
