Why getproperties and constructorof?

[aplavin]

By default, @batteries generate explicit getproperties and constructorof definitions:

StructHelpers.jl/src/StructHelpers.jl

Lines 53 to 54 in c316e30

	getproperties = true ,
	constructorof = true ,

Those definitions look very similar to default ConstructionBase fallbacks. Why are they needed at all? Differ in some corner cases?

They are equivalent. The potential advantage they have is that they don't involve generated functions. Though I don't know a practical example, where that makes a difference.
