Import syntax and module semantics are suboptimal. See #57 for a write-up. To summarize, this makes imports a map instead of a list: **before** ```yaml $import: - names: [capitalize,decapitalize] from: https://pls.pub/std@1.0.0/strings.yaml - names: [parse] from https://pls.pub/x/parse.yaml ``` **after** ```yaml $import: capitalize, decapitalize: https://pls.pub/std@1.0.0/strings.yaml parse: https://pls.pub/x/parse.yaml ``` This also simplifies the module semantics. Modules do not have a list of symbols and a value, they just have a value, and that value you can imported key by key: ```yaml $import: something: https://pls.pub/x/things@1.0.0/mod.yaml ``` Or, use the `<<` merge key after a symbol name to indicate that the _entire module value_ should be bound to that name. ```yaml $import: everything<<: https://pls.pub/x/things@1.0.0/mod.yaml ``` There is not currently a method to alias imported names, but that should be provide for eventually.

This also simplifies the module semantics. Modules do not have a list of symbols and a value, they just have a value, and that value you can imported key by key.
Or, use the
<<merge key after a symbol name to indicate that the entire module value should be bound to that name.It is possible to have both a slurp everything import and a named import:
