Unable to chain-access tuple types

[ustulation]

{Copying from here: http://stackoverflow.com/questions/29250677/unable-to-chain-access-tuple-types}
Given:

struct NameType([u8;64]);
name: (NameType, NameType);

i can do:

let def = &name.0   OR   &name.1

but i cannot do:

let def = &name.0.0   OR   &name.1.0

to access the internals. I have to do it twice:

let abc = &name.0;
let def = &abc.0;

why am i unable to chain it to access inner sub-tuples, tuple-structs etc?

&name.0.0 doesn't work because 0.0 is a floating-point literal. Either (&name.0).0 or &name.0 .0 works.

The compiler prints a help notice for &name.0.0:

test.rs:9:24: 9:24 help: try parenthesizing the first index; e.g., `(foo.0)`

Issue #20287 requested that &name.0.0 work, but it was closed. That issue has relevant links (e.g. the tuple indexing RFC and the weekly minutes where this issue was discussed).

Yes, this is currently not a bug, as @rprichard mentions.
