Is your feature request related to a problem? Please describe.
Currently, we check for every known token, and if any of them does not match, then declare it as a paragraph.

Describe the solution you'd like
Some sort of test mechanism should be implemented for paragraphs to parse consecutive lines at the same time

Describe alternatives you've considered
Build a paragraph test function analyzing how it is working now.

Additional context
Parsing time should be taken in mind.
