I often see a piece of code like this:
require "date" begin Date.strptime(some_string, some_format) rescue nil end
Since we now have (https://bugs.ruby-lang.org/issues/12732)
Kernel#Integer with a parameter to avoid raising an error in case of an invalid string, I think that having a counterpart of it in
Date would be convenient. I propose
Kernel#Date, which works like
Date.strptime except that it takes an optional keyword argument, and works as follows:
Date("2017/02/02", "%Y/%m/%d", exception: nil) # => #<Date: 2017-02-02 ((2457787j,0s,0n),+0s,2299161j)> Date("foo", exception: nil) # => nil

I have nothing against it per se but what happens to the Date namespace?
People may be confused when they see Date like the above that used to be part of the
require 'date' call, but now suddenly is part of Kernel.
On a side note though, not specific to the suggestion here, I think a more unified
and simpler way to handle time/date related code in ruby in general would be nice.

Thanks for the notification. I actually do think there should be a similar thing with
Time, and if
Date is supposed to become obsolete and be absorbed into
Time as the argument suggests, then
Kernel#Time would be convenient:
Time("23:55") Time("foo", exception: nil)
