Hi!
Is there any good idea how should a character represented in ruby? The
current one looks weird an is not intuitive, and more and more such
things are inserted into ruby (@@var as a class variable eg.) , so it
begins to look like a perl program (and one character change → another
program ) :-/
BTW is there any possibility to write blocks like we can write
for i in [1,2,5,2,6,1,6]
puts i
end
But that time the each iterator is called, if I’m right.
Can I use it with other procedures accepting a block?

Well, you know about “if str[0] == ?M”, obviously. What’s wrong with that?
OK, it’s not intuitive, but it’s easy to learn and harmless. I like it,
actually. Like so much else in Ruby, it economises typing without sacrificing
readability.
?c Ruby
‘c’ Most other languages
That’s a 33% saving in screen real estate for the reasonably common operation
of specifying a specific individual character.

for i in [1,2,5,2,6,1,6]
puts i

No, only each. I really like the “for a in x” syntax, but then when you make a
minor variation and have to use “each_with_index” instead of the implicit
“each”, the code looks inconsistent, so most of the time I use explicit “each”
now.
