Defining a solver type with macros

[juliohm]

I will create a separate thread for this question, this post is too long already:

Macros and modules

Suppose I have a base package with abstract types and interfaces called BasePackage, and a second package with developer tools that builds on top of the base package called DevTools. In the latter package, I define helper macros to facilitate the creation of new solvers with similar interface: DEVELOPER TOOLS ### BASE PACKAGE module BasePackage abstract type AbstractSolver end abstract type AbstractEstimationSolver <: AbstractSolver end abstract type AbstractSimulationSolver <: A…
