The fact that you know this makes it so usable.
I like educational code and I dislike rules.
I do not see why
    x = @a["b"].split rescue []
is bad code, only because
    x = @a[some_method()].split rescue []
is bad code.
But there is no account for taste, see Rick I improve my idiomatic
English thanks to you ;).

Cheers
Robert
