 ## Design
 
@@ -48,13 +48,12 @@ There are two main components proposed in this RFC:
 
 - patterns, which check if a value *matches* some definition; and
 - match expressions, which match one value to a collection of arms and return a consequence of the arm if it's pattern matches.
-The syntax is inspired heavily by [Rust's match expression](https://doc.rust-lang.org/reference/expressions/match-expr.html) and [pattern syntax](https://doc.rust-lang.org/reference/patterns.html) .
 
 The proposed grammar changes are below:
 
 ```ebnf
-namepattern = NAME | NAME '[' exp ']' | namepattern '.' NAME
-pattern = NUMBER | STRING | 'nil' | 'true' | 'false' | stringinterp | namepattern | '*' | pattern 'or' pattern | '(' pattern ')' | NUMBER 'until' NUMBER | 'not' pattern

 ### Patterns
 
 Patterns are the most powerful part of this RFC and without them match expressions would be next to useless. The syntax is designed to be extensible and flexible enough for use in other areas of the language in future.
