 - name mangler: Don't use keywords as an id.
 - `properties`: Optimize member expression with string properties.
 - `inline`: Inline some function expressions even if it's not fn-local.
 - `analyzer`: Track reassignment correctly.
 - `analyzer`: Track fn-local correctly.
 - `sequences`: Inject `void` if required.
 - `inline`: Inline function declarations correctly.
 - `sequences`: Merge expressions into test of if statements.
 - `sequences`: Reduce calls to an assigned variable.
