Evolving?Java?Without?Changing?the?Language
In?"The?Feel?of?Java"?James?Gosling?stated?that:?Java?is?a?blue?collar?language.?It's?not?PhD
thesis?material?but?a?language?for?a?job.?Java?feels?very?familiar?to?many?different?programmers
because?I?had?a?very?strong?tendency?to?prefer?things?that?had?been?used?a?lot?over?things?that?just
sounded?like?a?good?idea.
The?extraordinary?success?of?Java?offers?weight?to?the?notion?that?this?was?a?sensible
approach,?and?if?it?remains?an?important?goal?for?Java?today,?then?it?makes?sense?that?the
language?should?continue?to?evolve?relatively?slowly.?In?addition?to?this,?the?fact?that?Java?is?a
mature,?widely?used?language?causes?its?evolution?to?be?fraught?with?difficulty.?For?one?thing,
each?feature?added?to?the?language?can?change?the?way?it?feels?in?subtle?and?often?unpredictable
ways,?risking?alienating?developers?who?have?already?adopted?it?as?their?language?of?choice.
For?another,?a?feature?that?makes?perfect?sense?on?its?own?may?interact?with?other?features?of?the
language?in?awkward?or?unexpected?ways.?Worse,?once?a?language?feature?has?been?added?it?is?all
but?impossible?to?remove?even?if?it?turns?out?to?be?detrimental?to?the?language?as?a?whole.To
justify?adding?a?new?feature,?a?language?designer?must?be?highly?confident?that?it?will?be?of?long
term?benefit?to?the?language?rather?than?a?short?term?or?fashionable?solution?to?a?problem?that
rapidly?becomes?redundant.?To?mitigate?the?risk?a?language?designer?will?typically?experiment?by
creating?a?separate?language?or?branch,?such?as?the?Pizza?language?used?to?experiment?with?Java's
generics,?prior?to?their?implementation.?The?problem?with?this?approach?is?that?the?audience?for
such?experiments?is?both?small?and?self-selecting;?obviously?they?will?all?be?interested?in
