Cargo Features

This crate provides 2 feature flags, 1 enabled by default.

"debug_default"

Signal the build script to enable the "dyn_*" features in debug builds.

Enabled by default.

"dyn_closure"

Box closures at opportune places, such as Var::map, reducing the number of monomorphised types.

This speeds-up compilation time at the cost of runtime.
