Parsing bug / Operator precedence issue? when destructuring

[stefandd]

Bug in Boo (tested with trunk 0.9.7 and 0.9.4):
Destructuring from returned lists works fine with regular variables, but not with fields of either classes or structs. From the error message "unexpected token: ,." I suspect an operator precedence issue.

def bar():    
    return [1, 2]

class foo:
    public a as int = 0
    public b as int = 0

struct zoo:
    public a as int = 0
    public b as int = 0

f = foo()
z = zoo()

// This works
a, b = bar()
print a, b // prints  "1 2" as expected

// This DOESN'T
f.a, f.b = bar() // BCE0043: Unexpected token: ,.

// This DOESN'T
z.a, z.b = bar() // BCE0043: Unexpected token: ,.
