Ready for a review whenever someone has the time... thanks https://github.com/arrow-kt/arrow-core/pull/239

Have we decided to not have fold (as well as map, flstmap, etc) extensions for nullables values?

Not sure about that.... I went trough the arrow-core API and added Nullable equivalents to the functions that have

Option

in their public API

I was just wondering as there is a

fold

converted to

?.let { } ?: run { }

I'll try to have a better look tonight

yup,

fold

feels easier to type and read.... and the

?.let {} :? run {}

is the closes equivalent for a 1-1 replacement.....

Super! I'll have a look later, they were mostly trivial things :)
