I understand from documentation that Type aliases are pure syntactic sugar, and are not available at runtime.
However, I’m curious if it’s possible, by authoring a complier extension, to decorate usages with annotations.
@FpmlType("http://www.fpml.org/FpML-5/pretrade#PersonReference/firstName") typealias FirstName = String fun doSomething(firstName: FirstName)
Then, at runtime, this would become visible as:
void doSomething(@FpmlType("http://www.fpml.org/FpML-5/pretrade#PersonReference/firstName") String firstName)
So, the goal of the compiler extension would be to add the annotation wherever the typealias is used as a parameter.
Are the appropriate transpilation / generation hooks available within the compiler extension framework to see that a typealias was declared as a parameter, and to add the annotation?
