If I had the problem, I would object intensively:

  He wants to check whether the current user has 'View' permission
  for "mymethod".

  His code should always return a truth value and never raise
  an "Unauthorized" exception.

As reported in an earlier post, I cannot fully reproduce his observation.
I do not need "View" permission but I do need an
"Access Contents Information" permission.
As the code above does not access any contents of "mymethod",
this is definitely a bug. Not very serious, but nevertheless a bug...
