Currently, my goto implementation can generate 6 Errors:
'goto's not allowed outside of subroutines'
'goto attempt to branch into loop'
'Subroutine missing label (:xxx:)'
'Duplicate Label'
'Expected Label, not keyword'
'Label syntax is ":label:"'

and 1 warning:
'Unreferenced label'

Goto is not allowed at file level (must be in function
or procedure), and is not allowed to branch to a
deeper nesting. Sort of prevents all the 'interesting'
cases, I hope.
