Definitely no (for MRI, at least).

Which means that it’s effectively impossible to alter the behaviour,
without altering the source-code.

Thanks for the information.

ruby 1.9

prints “#{name} has 5 credits”

Is there any existent library (ruby 1.9) availbale, which enables an
alternative variable substitution, like e.g.

prints “&name has 5 credits”

class VarTester
$g = “global”
@@c = “class”

def f

def initialize
@i = “instance”
l = “local”
puts “#$g #@@c #@i #l #f #{l} #{f}”

#=> global class instance #l #f local function
