futureLogging breaks when asyncnet is imported

[FedericoCeratto]

Description

The futureLogging define breaks compilation. Steps to reproduce:

echo "import std/asyncnet" > myproj.nim
nim c -d:futureLogging myproj.nim

...
/usr/lib/nim/lib/pure/asyncfutures.nim(228, 47) Error: type mismatch: got <FutureVar[nativesockets.Port]>
but expected one of:
proc logFutureFinish(fut: FutureBase)
  first type mismatch at position: 1
  required type for fut: FutureBase
  but expression 'future' is of type: FutureVar[nativesockets.Port]

expression: logFutureFinish(future)
