GROOVY-12147 and default locales

Hi,

the pull request for this was already closed so I had no chance to=20
comment on it itself.

I think there is a discussion about default locales I would like to start.

My personal reality is that the default locale is useless. In fact it is=
=20
actually a pain to work around it and very often I have to use multiple=20
formats even for the same language. Not even the tests for GROOVY-12147,=
=20
which also adds methods based on default locals, test based on the=20
default locale. And I think they should.

I would like to start a potentially controversial discussion:

Do not support methods depending on the default Locale in GDM.

If we want to have a convenience variant without formatter or locale,=20
then let's define one format. I would especially remove that currency=20
variant introduced in that PR.

What do you guys think? I am especially interested in the opinion of=20
people that do not program for just one country/region. I for example=20
have very often programs in swiss/german/italian/french/english at the=20
same time. At least if it is more than just a small command line script.=
=20
Already when writing log files I may need a different format than what=20
my locale says.

bye Jochen
