You still fail to supply self-contained samples.

It still requires Qt (why, please just get rid of it because it has no
place in a parser).

There's no `main`. There's no sample input. There's no expected results.
There's no actual results. 

In short there's no viable question.

Ok.

Well. Why is that subgrammar repeated 3 times?

Also, `>` is an expectation point. As you might have guessed, an
expectation point declares a point at which a given parser is _expected_
to match. So `> '='` expects the `=` sign. If not, that's an unexpected
error and the parser throws.

The exception raised is `qi::expectation_failure<It>`. Quite expected.

If you wish to test for an alternative and be able to backtrack, do not
use expectation points in your sequence. Instead use the `>>` regular
sequence operator.


Is this your immediate problem?
