[CHANGES]
- Support suspend/resume within while loops and plain loop blocks
- Import the syntax keywords by default, rather than having to
request them as an import symbol
- Added some initial documentation to explain the new syntax
[BUGFIXES]
- Declare (for now) dependency on perl 5.24 to prevent older versions
from attempting it and failing. We hope to support older versions
back to 5.14 in due course.
