Using Nim Types in Constructors

Typedesc can be used as a parameter. This allows (via universal function call syntax) you to pretend you are asking the type to instantiate itself (or any other operation.) In theory since the parameter is then not used for anything and the function is inlined there is no overhead in the final product.

proc make*(not_used: typedesc[Thing]) {.inline.} = ...

foo = Thing.make
