* After parsing, compute level/displacement pairs for each variable
...
use site, allowing environments to be stores as vectors of values
rather than maps. This should speed up evaluation and reduce the
number of allocations.

* Change the semantics of "with" so that inner "withs" take
...
precedence, i.e. `with {x=1;}; with {x=2;}; x' evaluates to 2'.
This has a simpler implementation and seems more natural. There
doesn't seem to be any code in Nixpkgs or NixOS that relies on the
old behaviour.

* Use std::tr1::unordered_set instead of std::set for the symbol

table. This gives a 10% speed increase on `nix-instantiate
/etc/nixos/nixos -A system --readonly-mode'.

* Evaluate lets directly (i.e. without desugaring to `rec { attrs...;
...
<let-body> = e; }.<let-body>). This prevents the unnecessary
allocation of an attribute set.

* Use a symbol table to represent identifiers and attribute names

efficiently. The symbol table ensures that there is only one copy
of each symbol, thus allowing symbols to be compared efficiently
using a pointer equality test.

then the blackhole has to be removed to ensure that repeated

* Make `derivation' lazy again for performance. It also turns out

that there are some places in Nixpkgs (php_configurable /
composableDerivation, it seems) that call `derivation' with
incorrect arguments (namely, the `name' attribute missing) but get
away with it because of laziness.
