WP_Block_Parser::proceed() public WP 3.8.0

Processes the next token from the input document and returns whether to proceed eating more tokens

This is the "next step" function that essentially takes a token as its input and decides what to do with that token before descending deeper into a nested block tree or continuing along the document or breaking out of a level of nesting.
