- Avoids a bug when the index in the lookup is out of range.
- Added some tests for #has() and #length
- Removed stash.debug(). Now it will warn when keys don't exist (use #has() to avoid)
- Added Stash#has(key)
- Added Stash#length
- Hide the warnings behind a debug flag (controlled by stash.debug())
- Added Stash#empty
- Added travis conf
- Initial commit. Tests pass.
