I have just tried playing with Julia and I find myself often copying `immutable` objects while changing just one field:
function setX(pt::Point, x::Float64) # Only changing the `x` field return Point(x, pt.y, pt.z, pt.color, pt.collision, pt.foo, pt.bar); end Is there is any syntactical sugar to avoid having to write out all the other fields which are not changing (e.g. pt.y, pt.z, etc.) while creating a new object? Apart from making the function much easier to understand, this will also make it much less of a hassle to change fields on the type. Thanks.
