trying to make produces the error:

test.nim(72, 5) Error: invalid type: 'T' in this context: 'Property'
(1 of 1) error: invalid type: 'T' in this context: 'Property'

Which is wery confusing. In some moment i had probably the same error telling something about bad template initialization, which is even more confusing (now i can't reproduce it)

In case it's not clear: error string is of tArray: arrayValue: seq, there seq should have [type] attribute
