@youtux @olegpidsadnyi Please review

[bbatliner]

This is exactly the patch I was expecting to see after encountering KeyErrors related to the parameterization example in the README with the <start> syntax.

However, Oleg's comment on the related issue suggests that this feature will be removed in the future?

Am I understanding this correctly? Why would this be removed?

[elchupanebrej]

Yes, this feature will be removed. An approach where a test is parametrized inside python code and this parametrization is used in Gherkin scenario definition is broken "by design" because hides some information that has to be present in Examples, so you couldn't share your scenario with stakeholders without losing some information needed for scenario execution.
I found that there is some backward incompatibility and created this patch. But with approval from core maintainers, I'll close this patch after removing rudiments of old approach
