Okay, this time I only counted string interpolation... brianhempel (Brian Hempel)

04:38 PM Ruby Feature #10481: Add "if" and "unless" clauses to rescue statements

You’re right there may be some risk for anti-patterns, but from my experience this example in the original proposal is practical:
~~~ruby
begin
...
rescue => e if e.message == "some error"
...handle error...
end
~~~

In the ruby/ruby repo, the shorthand is used 115 times, regular is used 12,473 times. (12,473 is all regular ... brianhempel (Brian Hempel)

Good catch: No, I did not. I'll try to get better n... brianhempel (Brian Hempel)

04:53 AM Ruby Misc #10541: Remove shorthand string interpolation syntax

Steve Richert asked me how many of those 353,199 regular interpolations could have been replaced by shorthand interpolations, since most string interpolations will contain a local variable, a method, or a more complicated expression.

08:16 PM Ruby Misc #10541: Remove shorthand string interpolation syntax

I analyzed the ~150,000 Ruby files in the top 1000 Ruby repositories on GitHub:
The regular interpolation syntax is used 353,199 times.
The shorthand interpolation syntax is used 1,376 times.
In percentages, that's 99.6% vs 0.4%. ... brianhempel (Brian Hempel)

08:38 AM Ruby Feature #10552: [PATCH] Add Enumerable#frequencies and Enumerable#relative_frequencies

Yes, I would rather see `Hash#map_values` in Ruby before `Enumerable#frequencies`. However, if both `map_values` and `frequencies` were added, then we might not need `relative_frequencies`, since calculating it becomes cleaner:

07:29 PM Ruby Feature #10552: [PATCH] Add Enumerable#frequencies and Enumerable#relative_frequencies

Thanks for the feedback David. I can see a `map` functionality being useful, but here I will play some arguments against integrating `map`:

07:59 AM Ruby Feature #10552 (Open): [PATCH] Add Enumerable#frequencies and Enumerable#relative_frequencies

Counting how many times a value appears in some collection has always been a bit clumsy in Ruby. While Ruby has enough constructs to do it in one line, it still requires knowing the folklore of the optimum solution as well as some acroba... brianhempel (Brian Hempel)
