Another version of this patch with a light-hearted commentary, using the sa=
me algorithm but a slightly different approach, is available at: <a href=3D=

Ruby is a mature, productive programming tool. It=E2=80=99s not a silly toy=
. It doesn=E2=80=99t deserve to have such dumb bugs lurking inside its core=
 classes.

That=E2=80=99s just me, exercising my right to politely protest the decisio=
n made by Ruby maintainers. I hope they would reconsider and fix it interna=
lly.
