sorbet-unwrap: debugging inside T.let / T.cast still a problem

[md-work]

Sadly sorbet-unwrap won't help if there's a method call inside T.let(..., or T.cast(..., .

 

Proposal: sorbet-unwrap could overwrite T.let / T.cast with a minimal implementation, which simply forwards the first argument and ignores the second.

module T
  def self.let(value, type, checked: true)
    value
  end
  
  def self.cast(value, type, checked: true)
    value
  end
end

 

Sadly I've no idea how the evaluation of the second parameter may be skipped. This would be a problem, if the second parameter is something like T::Array[Integer] because there will be code to step trough.
