Detailed Description

Object authorising R 'break' and 'next' commands.

LoopScope objects must be declared on the processor stack (i.e. as C++ automatic variables). Each Environment object keeps track of the number of LoopScope objects associated with it. The R commands 'break' and 'next' are legal only when the evaluation Environment has at least one LoopScope in existence; this can be determined by calling Environment::loopActive().
