Utility function that provides a bit cleaner interface
for running a parser over a string.
Returns undefined in case parser did not match.
Input string is broken down to characters as [...str]
unless you provide a pre-split array.
Note: this doesn't capture errors thrown during parsing.
Nonmatch is considered a part or normal flow.
Errors mean unrecoverable state and it's up to client code to decide
where to throw errors and how to get back to safe state.
