indexmap support?

[SamuelMarks]

Would be great to have. Currently get this error:

|
| subst::substitute(input_as_utf8, &env.into());
| ^^^^^^^^^^^^^^^^^ cannot infer type of the type parameter M declared on the function substitute
|
= note: cannot satisfy <_ as VariableMap<'_>>::Value == _
help: consider specifying the generic argument
|
| subst::substitute::(input_as_utf8, &env.into());
| +++++

Where env is indexmap::IndexMap<String, String>.

Obviously I can just do the non ergonomic:

let mut hm = std::collections::HashMap::<String, String>::with_capacity(env.len());
for (k,v) in env.iter() {
    hm.insert(k.to_owned(), v.to_owned());
}

I agree, indexmap support makes sense! PR #25 opened to implement it (behind a feature flag).
