Infix "operator" fails in indexing

Created by: r3m0t

Example:

macro @ {
case infix { $val:expr | _ $x:ident (.) ... } => {
return #{$val}
}
}

var x = y[i]@a.b.c.d[0]; // works
var x2 = (y[i]@a.b).split(','); //works
//var x3 = (y[i]@a.b).split(',')[0]; //broken
var x4 = y[i]@a.b[0]; //works
//var x5 = (y[i]@a.b)[0]; //broken
