Try to write a parser for es6, is this the right place for question about
syntax?
There is no expression or statement start with =>, same goes to yield [no
LineTerminator here] * AssignmentExpression ?
yield [no LineTerminator here] * AssignmentExpression
has the line terminator restriction because yield without the * has the same
restriction:
yield [no LineTerminator here] AssignmentExpression
And that one has that restriction because there exists a third form of yield
that doesn't take an expression:
yield
This is the same situation as with return statements, which also take a [no
LineTerminator here] restriction. It's a convenience to prevent return from
capturing the expression from the next line for the users (I'm not among them)
who like to rely on semicolon insertion:
if (error) return
x = y
