[Haskell-cafe] [ANN] acme-dont-1.2 - a "don't" construct

[Henk-Jan van Tuyl]

The `don't` function is a big step forward in computering; it will surely
prevent many bugs from occurring, with little effort to software
developers.

Is it published in a scientific magazine yet?

Regards,
Henk-Jan van Tuyl
