How do I create a class instance from a string name in Crystal?

Question

I want the Crystal equivalent of this:

clazz = 'ExampleClass'.constantize # Rails
clazz = Object.const_get('ExampleClass') # pure Ruby
obj = clazz.new

You can't, these kind of dynamic aspects are not possible in Crystal.

However, macros can take a long way. Please read this similar issue and discussion:
