It seems indeed to be non-ambiguous, though I'm not sure allowing this syntax is a good idea. It is, after all, only readable by people very comfortable with the different input types. We'll explore this. > The man page describes other COUNTx usages: > > % man enum | nl | grep COUNTx | grep -v LEFT > 107 o enum .. COUNTx STEP .. RIGHT > 112 o enum .. COUNTx STEP .. > 113 o enum ..

The others you're suggeting would be convenience shortcuts which we'll consider, though I'm not sure the introduced lack of readability is a good idea. We'll ponder about it. Thanks anyways for trying to make enum better! Hauke -- .''`.
