This is a package I use to handle numerical-model parameters, thus the name. However, it should be useful otherwise too. It has two main features:
- keyword type constructors with default values, and
- unpacking and packing of composite types and dicts.
The keyword-constructor and default-values functionality will probably make it into Julia (# 10146, #533 and #6122) although probably not with all the features present in this package. However, there is
Base.@kwdef which covers many of the use cases of Parameters.jl's keyword constructor. I suspect that this package should stay usable & useful even after this change lands in Julia. Note that keyword functions are currently slow in Julia, so these constructors should not be used in hot inner loops. However, the normal positional constructor is also provided and could be used in performance critical code.
