### [`heapsize`](heapsize)
-A complete working Macros 1.1 implementation of a custom derive. Works on any
-Rust compiler >=1.15.0.

-### [`heapsize2`](heapsize2)
-
-The equivalent of the previous example but using fancy new APIs from the nightly
-compiler. It illustrates some neat features of the hygiene system of Macros 2.0
-and shows how to leverage those to provide amazing error messages to users.
-Currently requires a nightly Rust compiler >=1.24.0-nightly but we are working
-to stabilize all of the APIs involved.
