Syntax for communication has a reasonable circle of uncertainty which is why compiler parsers are easier than natural language parsing. Yeah it matters lots when you're typing into your calculator.
As for what part of equals do I not get? I feel syntax is way less important than the meaning, the two are not even a little bit equal.
Sorry I feel like I'm attacking a straw man here - I mean no disrespect but this subject gets me going. Some folks really are caught up by grammar and form. How about this: "Grammar is to language as pre-genetics botany is to plants." Yeah?
