Mention `--allow-eval` in README #277

Closed utdemir closed 4 years ago

I just learned it on a random conversation, and it was a huge time-saver for me; so thanks a lot for that feature.

However it was just by chance that I learned it, and even after that it took me a while to figure out how to use it (mainly which prefix to use). It'd be nice to have it mentioned on README.md, so more people can benefit from it.

I was only the reviewer for the feature, @isovector contributed the implementation. Agreed it would be good to document. @isovector, so you want to suggest any text? Or alternatively, do you @utdemir want to suggest anything? Happy to take either a PR or a paragraph in this issue that I'll slot in the README.

I dunno. It just finds comments of the form -- $> foo and runs them as foo in the repl session. I stole the idea from Unison if you want to steal some of their documentation (search for watch expression in that link).

I'm not sure if it would be helpful to add any of it to the readme, but I decided to write up this blog post about the feature: https://jkeuhlen.com/2019/10/19/Compile-Your-Comments-In-Ghcid.html. I'd be happy to add any of that content or write up a smaller blurb on usage for the README if desired.

Done in https://github.com/ndmitchell/ghcid/blob/master/README.md#evaluation. I linked to your blog @jkeuhlen - thanks!
