* Add a PermissiveRespondTo extension for MashesMichael Herold2019-11-171-0/+44
| | | | | | | | | | | | | By default, Mashes don't state that they respond to unset keys. This causes unexpected behavior when you try to use a Mash with a SimpleDelegator. This new extension allows you create a permissive subclass of Mash that will be fully compatible with SimpleDelegator and allow you to fully do thunk-oriented programming with Mashes. This comes with the trade-off of a ~19KB cache for each of these subclasses and a ~20% performance penalty on any of those subclasses.

* Add an extension to maintain original Mash keys (#326)Michael Herold2017-02-221-0/+28
One of the behaviors of Mash that we see regularly surprise users is that Mash stringifies any keys passed into it. This leads to unexpected lack of synergy between Mash and its cousins (particularly Dash), since the property DSLs do not handle indifferent key access. This extension ensures that the original keys are kept inside the Mash's data structure, at the expense of more costly logic for fetching information indifferently. I have included a benchmark that compares the two. The benchmark shows that when you are passing string keys into a Mash, using this extension will actually be _faster_ than the default implementation, but that the reverse is true when passing symbol keys. In #296, I tried to do this universally for all Mashes, which slowed down the fetching behavior for Mash significantly. I like this attempt much better because it allows users to opt into the new behavior if they want it, while still keeping the default implementation as-is. Fixes #196 by giving the option of keeping the original structure of the Mash when using it with Dash. Fixes #246 by giving the option of opting into keeping the original keys. Closes #296 by giving a more flexible path forward that doesn't change the semantics of the main Mash class.
