Of course:

  irb(main):001:0> require "nolocal-spike"
  => true

  irb(main):002:0> class C
  irb(main):003:1>   attr_accessor :a, :b, :c
  irb(main):004:1>   def initialize &blk
  irb(main):005:2>     instance_eval( &nolocal( &blk ) )
  irb(main):006:2>   end
  irb(main):007:1> end
  => nil

  irb(main):008:0> C.new do
  irb(main):009:1*   a = b = 5
  irb(main):010:1>   c = a + 2
  irb(main):011:1> end
  => #<C:0x2fce8e0 @c=7, @b=5, @a=5>

Two years ago I was experimenting with modifying the AST using plain
Ruby. (On Windows, I couldn't use parsetree for example back then.)
The code above is one of the results. The same should be easy with the
actual libraries.
