@JanisErdmanis Here's the changes you brought up

[JanisErdmanis]

The test set looks good. Perhaps it could be improved with a case when package which depends on Oxygen is loaded as a module to check if there are any precompilation errors. I think that can be automated by creating a dummy package which can be put within a test directory and added to a LOAD_PATH which would then be treated as ordinary package with precompilation.

@ndortega can we also add a method:

get(collection, key) = Base.get(collection, key)

Since users or package developers may want to overload get method this way. Perhaps even safer strategy here is:

get(args...) = Base.get(args...)
get(args...; kwargs...) = Base.get(args...; kwargs...)

We need to comment out in Oxygen.jl with this pull request:

import Base: get

Because otherwise we have

import Base: get
get(x, y, z) = Base.get(x, y, z)

and thus if method is not found it would form a recursion. The removal of import Base: get is also good as that eliminates type piracy.

An alternative is putting the redirection get methods within the @oxidise macro itself.
