You are still confouding rules for writing with rules for parsing. It's absolutely possible and easy to make rules making writing easier but parsing harder.
For example, if you make rule that makes formatting markers like **\_ be order insensitive (so **_word**_ formats same as **_word_**), much easier for user, as they don't need to remember order of which the operators were used, harder to code (I assume)
