investigate @krux02's proposal for tryExpr, see nim-lang#12076 (comment)

@krux02 I don't see how this could be implemented with a macro:

when overloadExists(callNeedingNetwork(url)):
  setupNetwork()
  callNeedingNetwork(url)

If you disagree please provide some code.

Well unfortunately I think this will not work. It already doesn't work for arrays. Imported generic procs will always be hidden by local untyped template. After all this was just a quick experiment.
