notes on Ruby Tail Call Optimization
View tail-recursive.rb
# First, I suppose you have ruby 1.9.1 or 1.9.2
# Open irb. Execute this:
# RubyVM::InstructionSequence.compile_option = { tailcall_optimization: true, trace_instruction: false }
# Note, RubyVM::InstructionSequence.compile_option() doesn't have item :trace_instruction, still, you need to specify it. WTF?
# Also, it doesn't work if you just put it to the script. Don't know why yet. Tell me (@rofh) if you know.
# Then open the file:
# require "./tail-recursive"
# Then execute function:
# fact(30000)
