more newbie help with classes and methods please

[Morton Goldberg]

I try (not always successfully) to avoid deeply nested constructs.
When I can't escape nesting, rather than directly nesting, I favor
writing something like:

def case_A
case
when ...
when ...
end
end

def case_B
case
when ...
when ...
end
end

case
when condition_A then case_A
when condition_B then case_B
end

Glad to be of help.

STDIN is indeed a constant defined in Module and its value is the
standard input stream (which is an instance of IO). To me the strange
thing is that Kernel#gets is OK, but Kernel#getc is deprecated.

Well Kernel#gets is ARGF#gets. ARGF is (in general) for writing well-
behaved filters. Well-behaved filters work on a line by line basis
usually. However ARGF.getc is not deprecated. This makes me think
Kernel#getc is not ARGF.getc, but probably STDIN.getc. This is
inconsistant with Kernel#gets and could thought to be confusing.
Hence its deprecation. Just one man's theory.

Very confusing. Surely it would have been easier to keep getc as a
Kernel method. gets and getc are both very similar. Could someone ask
Matz when next they see him?
