Take a new struct Variables instead of two &mut [] vectors for static and dynamic variables.
Replace all potentially-failing operations with Err returns and add tests. Remove the Char parameter type; characters are represented as Numbers. Fix integer constants to work properly when there are multiple constants in the same capability string. Tweak loop to use iterators instead of indexing into cap.
Implement the %?, %t, %e, and %; operators. Also implement the %<, %=, %> operators, without which conditionals aren't very useful. Fix the order of parameters for the arithmetic operators. Implement the missing %^ operator.

Implement conditional support in terminfo, along with a few other related operators. Fix implementation of non-commutative arithmetic operators. Remove all known cases of task failure from `terminfo::parm::expand`, and change the method signature. Fix some other miscellaneous issues.

It's a bit late for this, but does this do the correct thing? I would've though the copy means that mparams[0] and mparams[1] are not modified by the +='s below.

Hah, good point. I don't think the tests covered this case.

Add `needless_bitwise_bool` lint fixes rust-lang#6827 fixes rust-lang#1594 changelog: Add ``[`needless_bitwise_bool`]`` lint Creates a new `bitwise_bool` lint to convert `x & y` to `x && y` when both `x` and `y` are booleans. I also had to adjust thh `needless_bool` lint slightly, and fix a couple failing dogfood tests. I made it a correctness lint as per flip1995's comment [here](rust-lang/rust-clippy#3385 (comment)), from a previous WIP attempt at this lint.
