Issue

The "Full Example" of using @truffle/contract to interact with contracts should include an example of listening to an event with a filter.

In the past, it used to be possible to pass a filter object on indexed event parameters when listening to an event, as seen for example [here](https://ethereum.

When passing Wasm function to the host as a callback, it's passed as an index in the table.
Wasm3 needs to provide an API to call such functions.

Hardhat doesn't support solc remappings.
We should print a warning if we detect that a user is trying to use them via their config.

Each contract has its own Lua stack.
To advance over several events, use coroutines.

We can safely disallow any use of solc below 0.4.25.

Most users who use event listeners do not have use for the log noise produced by this.

Make this printing optional or remove all together.
