Consecutive syntax definition

[rizo]

How will the following syntax rule be parsed?

syntax "let" x "=" v
let x = 1

Since let is not defined while syntax is parsed it will be treated as an argument:

syntax "let" x "=" v let x = 1

This issue should be taking into consideration during the definition of the standard syntax rule. Special care is needed because syntax defines it's own local scope. let-like rules have to be added to the global scope.
