In Python the syntax to create 1-tuple is *(element,)*. Note the ",". It's
not the most beautiful but is acceptable.

Hi
I understand the lack of distinction between a unit type and a 0-tuple, http://www.haskell.org/pipermail/ since they are isomorphic.
It's more we pronounce 0-tuple as unit, they are identical.
But it is strange that there is no 1-tuple, since _|_ and the 1-tuple (_|_) would be different things entirely, no?
Yes, it would be useful, but what would the syntax be? (x) already means something else - namely grouping. Yhc defines both Tuple1 and _E, both of which are the 1-tuple. I'd like it if there was a standard definition Box for the 1-tuple, in the base libraries.
