We're able to generate function template/snippets for callbacks since a while back. But, given that the type information has no name for unlabelled arguments, we've been forced to call most variables in the generated template
v
(with a few notable exceptions that we've special cased).This PR improves how we infer template variable names by looking at the type path. For example, the type
Environment.t
would be calledenvironment
in templates, whereasEnvironment.envConfig
would be calledenvConfig
.This can help the DX quite a lot, because we can capture some of the variable name intent, at least for more complex types.

I think this will be quite useful, but interested in hearing more thoughts.
