Currently using
IndexOfOrNone
on a concrete immutable collection such asImmutableArray
orImmutableList
results in an ambiguous overload error.This was not directly fixable using
[OverloadResolutionPriority]
since the conflicting extension methods are in two different classes.I moved the immutable list overloads to
ListExtensions
but kept the old methods around to avoid a binary breaking change. I only removed thethis
modifier (which is not a binary breaking change, see #346)This PR is probably best reviewed on a per-commit basis :)
