Expand description

Allow loop { ... } expr returns a value via break value.

Note

Syntax

Four forms of break will be supported:

  1. break;
  2. break 'label;
  3. break EXPR;
  4. break 'label EXPR;

where 'label is the name of a loop and EXPR is an expression. break and break 'label become equivalent to break () and break 'label () respectively.
