Expand description

Similar to Issue, but contains some extra information

Variants

`Invalid(ProvidedIdx, ExpectedIdx, Compatibility<'tcx>)`

The provided argument is the invalid type for the expected input

`Swap(ProvidedIdx, ProvidedIdx, ExpectedIdx, ExpectedIdx)`

Two arguments should be swapped

`Permutation(Vec<(ExpectedIdx, ProvidedIdx)>)`

Several arguments should be reordered
