#1947 landed a new t.try() assertion. It's experimental, one of the reasons for which is that we don't have documentation yet.

We need to document the assertion, how to use it and what the edge cases are.

Apologies for how bare this issue is — happy to elaborate more if you're looking to contribute this 😍

Version: N/A

For users who are interested in using Akka.Persistence.Query, CQRS, EventSourcing, projections, and so forth - the only practical way to combine data from multiple persistent entities without knowing in advance what those entity IDs are is to use Akka.Persistence.Query's EventsByTag queries.

It appears in Ruby 2.2 a change by @nobu modified the logic to just call String#index when passing a String to String#gsub, rather than always using a Regexp object and paying the cost to compile it every time.

Hi there!

I found this framework interesting and promising due to its handy API syntax. However, the documentation somewhat confuses me. Well, this is unsurprising because I'm not an expert in Web development anyway. Actually, I have received little formal education in CS, but I know the very basics of TCP thanks to [Beej's Guide to Network Programming](http://beej.us/guide/bgnet/html/single/bg

You can’t perform that action at this time.
