Taus 131ec8d22f Python: Handle loop constructs outside of loops 
Observed on some test files in Nuitka/Nuitka, having `break` and
`continue` outside of loops in Python is (to Python) a syntax error, but
our parser happily accepted this broken syntax.

This then caused issues further downstream in the control-flow
construction, as it broke some invariants.

To fix this we now skip the code that would previously fail when the
invariants are broken.

fix
  • Using the break and continue keywords outside of a loop, which is a syntax error but is accepted by our parser, would cause the control-flow construction to fail. This is now no longer the case.
