The static binaries for the various interpreters and conversion utilities (i.e. `dhall`/`dhall-to-yaml`/`yaml-to-dhall`) are all roughly 10 MB each
The following languages natively bind to Dhall:
* Haskell * Clojure * Ruby
... and the following language bindings are in progress:
* Rust * Go * Python * PureScript
In the absence of a native language binding, you can convert Dhall to YAML or JSON and read that in.
