Drops the paste crate and does not bother to use #[wasm_bindgen] to generate the exported init function. Instead, exports a plain extern "C" function and uses uses #[export = name] to set its name, as wasm-bindgen would have done.

This is both simpler, and also does not require that the calling crate have wasm_bindgen as a direct dependency, so it fixes #1 at the same time.

I don't know how to solve this, but the #[wasm_bindgen] proc macro does not appear to support renaming the wasm_bindgen crate to something else, and refers to the module path wasm_bindgen in the expanded output. This causes wasm_init! to not compile if the caller does not itself depend on wasm_bindgen.

I implemented a replacement for the inventory crate using ctor and wasm-init. Calling inventory::submit! without depending on wasm_bindgen produces get the following output:
