It lets your write lambdas with 'slots' without inventing names for the parameters.

[s| ı + ı |]  =  \x y -> x+y

I have no background in this 'slot lambda' and a search reveals this package as the only hit.

Which may explain why I find the example given confusing. Why would [s| 1+1 |] not be equivalent to \x->x+x ?
