I’ve been messing around with the idea of streamlining dynamic dispatch on values for non hot path / glue code. The pattern is for multiple dispatch to dispatch to a function I define with a macro based on the known type information, and then the macro generated function dynamically dispatches based…

I don’t quite understand the usecase of this macro tbh. I think it is much clearer to just write out the function normally: function epw(v::Vert) label(v) == "C2" && return inf_epw(v) # special case return sup_epw(v) # default / else case end Maybe you could make an example where your ma…

To save some clicks, this is roughly what it expands to: (Main.M1) julia> @macroexpand @dispatch_on_value_noeval epw(v::Vert) begin label(v) == "C2" => inf_epw(v) # special case true => sup_epw(v) # default / else case end :(f…

I did a poor job explaining the actual use case, but this is an exercise in exploring meta programming as a way to automatically output optimal Julia code depending on the inputs. For instance say you want to generate a function that selected a function based on several values. A macro could go thr…

I am not entirely sure as I do not fully understand your usecase, but 2 interesting packages in that area might be ValSplit.jl and Virtual.jl.
