  The snippet below outputs 4 strings, "" , "" , "c" , "---"

  Im not exactly a regular expression guru, but shouldnt it output the following??: "c" , "---" , "---" , "---"

  var rex=re"(a)|(b)|(c)|(d)"

  var seq=["---","---","---","---"]

  discard matchLen("c",rex,seq)

  for i in seq:

  echo(i)

  -Robert

  Well, the beviour is correct. Keep in mind that () creates a capture, it is not only used for grouping. So you have 4 captures and the 3rd matched. To get want you want, use re"(a|b|c|d)".
