500 :: How to check for an explicit symbol in a module?

  Give the following files, a.nim:

  
  proc `/`*(a, b: string): string = a & "-a-" & b
  Run

  b.nim:

  
  proc `/`*(a, b: string): string = a & "-b-" & b
  Run

  and m.nim:

  
  import a, b
  
  echo a.`/`("x","y")
  echo b.`/`("x","y")
  
  when defined(`a./`):
    echo "a variant defined"
  elif defined(`b./`):
    echo "b variant defined"
  else:
    echo "No proc defined"
  Run

  Running nimrod c -r m I get:

  
  x-a-y
  x-b-y
  No proc defined
  Run

  I tried different combinations of the symbol for defined but wasn't able to make it work. How can I check that this / symbol exists?

  Have you tried the following?

  
  When defined(a.`/`):
    ...
  Run
