Wrong syntax rule

[sz73]

From chapter 1

The equation 3+ =3 is illegal because even though + and = are legal tokens, you can’t have one right after the other.

Actually, the equation is wrong in Julia because of the whitespace, not because of the order of the tokens (besides it is an invalid assignment anyway).

The following commands are both valid

a =+ 3
a += 3

Maybe have another example for syntax like

a = ) 1

All tokens are valid, but the ")" is unexpected
