Every time I think I would like to learn a new language, I quite quickly run
into some obvious feature that Python has but the newer language lacks, and
I think "bugger this for a game of soldiers" and abandon it. E.g. Ruby and
the lack of keyword arguments. Oh, I see Ruby 2.0 added them to the
language! Perhaps it's time for me to give Ruby a go again?
Ah, wait, I forgot Ruby's brilliant "feature" that whitespace *between*
expressions is significant:
[steve at ando ~]$ cat ~/coding/ruby/ws-example.rb
b = 1
print "a + b => ", (a + b), "\n"
print "a+b => ", (a+b), "\n"
print "a+ b => ", (a+ b), "\n"
print "a +b => ", (a +b), "\n"
[steve at ando ~]$ ruby ~/coding/ruby/ws-example.rb
a + b => 7
a+b => 7
a+ b => 7
a +b => 3
A shiny new penny for any non-Ruby coder who can explain that!
