Issue #10042 has been updated by Boris Stitnicky.
Nooo! Don't remove tail rescue! I suggested to introduce tail "resc" keyword with exception to be rescued somewhere here.

Feature #10042: Deprecate postfix rescue syntax for removal in 3.0
https://bugs.ruby-lang.org/issues/10042#change-49110

----------------------------------------
The postfix rescue notation is convenient...but almost always is a really bad antipattern.
An example of the notation:
Integer(f) rescue f # returns f if it is not parseable as an Integer
It silently ignores all StandardError raised by a piece of code...which often covers *many* more exceptions than the user *wants* to be ignoring.
It also hides the cost of constructing and throwing away all those ignored exceptions.
I believe Matz has even said in the past that he regrets adding the feature.
In any case, I propose that "rescue nil" should be deprecated with a warning (either always on or only when verbose) and we should plan to remove it in 3.0.
Who's with me?!
