Spec should allow arbitrary parentheses around expressions (section 4). #65

Closed cscott closed 10 years ago

cscott commented 11 years ago

In the general syntax rules, the spec should mention that arbitrary parentheses should be permitted. That is, if the syntax rule in the spec says:

x:Identifier = +x:Identifier; it is intended that the following all match this rule: x = +x; x = +(x); x = +((((x))));

You should also be clear whether parentheses are allowed around local function definitions, since those could in theory be parsed either as statements or as expressions. I believe the ECMAScript grammar causes them to be parsed as statements, therefore parenthesization is not allowed, but this should be specifically stated.
