Incompatibility with gcc 8

[Pesa]

Compilation with gcc 8 fails after commit 483f220. The error is:

  scope-lite.hpp:831:27: error: invalid use of ‘this’ at top level
           scope_noexcept_op(this->exit_function())
                             ^~~~

Thanks @Pesa, hopefully fixed now.

The error is different now (see below) but it still fails :(
Maybe just drop the noexcept altogether for gcc < 9 ?

scope-lite.hpp:832:46: error: there are no arguments to ‘exit_function’ that depend on a template parameter, so a declaration of ‘exit_function’ must be available [-fpermissive]
           scope_noexcept_op( scope_noexcept_op(exit_function()) )
                                                ^~~~~~~~~~~~~
[...]
scope-lite.hpp:832:46: note: (if you use ‘-fpermissive’, G++ will accept your code, but allowing the use of an undeclared name is deprecated)
           scope_noexcept_op( scope_noexcept_op(exit_function()) )
                                                ^~~~~~~~~~~~~

Ah, thanks, will do that.

Works fine now. Tested with gcc 8 through 13 and clang 7 through 18. Thanks a lot for the quick fix!
