You have to be careful not to characterise that aversion to
abbreviation as an absolute. 'enum' instead of 'enumeration' for
Of course we also don't say
MULTIPLY x BY 2 GIVING x
We instead say
x *= 2;
but then we wouldn't want to reinvent the overly verbose wheel.
I agree though that there is a challenge to make Java language
extensions feel like language growth rather than mutation but I would
still hope the aim is to enhance function and maintain readability -
I'm less worried about 'style' given that this language is a tool and
not some fashion item.
I'm also just not sure it's as objectively black and white as you make
out nor am I sure that everything java is a good thing (such as the
verbosity of some constructs).
I for one wouldn't mind adding keywords if they clearly and surely
improve readability. Altering programs that are broken by such
changes are generally fairly easily corrected with tools to help --
and unless we choose poorly, it's unlikely a new keyword will have the
impact that introducing assert did. Assert was so heavy used in
testing frameworks, pervasively used across the market and across each
source-base - not every word is so heavily used as identifiers in
I look forward to seeing more proposals, there are some (in part and
sometimes in full) that sound quite reasonable and I can see myself
finding a use for them.
