Local Variables
Synopsis
foo
Local variables begin with a
lowercase letter or _. The scope of a local
variable ranges from class,
module, def, or
do to the corresponding end or
from a block’s opening brace to its close brace
{}. The scope introduced by a block allows it to
reference local variables outside the block, but scopes introduced by
others don’t. When an uninitialized local variable is
referenced, it is interpreted as a call to a method that has no
arguments.
