of(p1) public

Returns the instruction sequence containing the given proc or method.

For example, using irb:

# a proc
> p = proc { num = 1 + 2 }
> RubyVM::InstructionSequence.of(p)
> #=> <RubyVM::InstructionSequence:block in irb_binding@(irb)>

# for a method
> def foo(bar); puts bar; end
> RubyVM::InstructionSequence.of(method(:foo))
> #=> <RubyVM::InstructionSequence:foo@(irb)>

Using ::compile_file:

# /tmp/iseq_of.rb
def hello
  puts "hello, world"
end

$a_global_proc = proc { str = 'a' + 'b' }

# in irb
> require '/tmp/iseq_of.rb'

# first the method hello
> RubyVM::InstructionSequence.of(method(:hello))
> #=> #<RubyVM::InstructionSequence:0x007fb73d7cb1d0>

# then the global proc
> RubyVM::InstructionSequence.of($a_global_proc)
> #=> #<RubyVM::InstructionSequence:0x007fb73d7caf78>
