This and other recursive references to the object(s) being defined will be checked for initialization-soundness at runtime through the use of a delayed reference. This is because you are defining one or more recursive objects, rather than recursive functions. This warning may be suppressed by using '#nowarn "40"' or '--nowarn:40'.

This expression uses the implicit conversion 'DateTimeOffset.op_Implicit(dateTime: DateTime) : DateTimeOffset' to convert type 'DateTime' to type 'DateTimeOffset'. See https://aka.ms/fsharp-implicit-convs. This warning may be disabled using '#nowarn "3391".

This construct causes code to be less generic than indicated by the type annotations. The type variable 'T has been constrained to be type 'int'.

This construct causes code to be less generic than indicated by the type annotations. The type variable 'Functor has been constrained to be type 'Functor'.

This construct causes code to be less generic than indicated by the type annotations. The type variable 'Applicative<'T> has been constrained to be type 'Const<'a,Result<'b,int>>'.

The instantiation of the generic type 'Const' is missing and can't be inferred from the arguments or return type of this member. Consider providing a type instantiation when accessing this type, e.g. 'Const<_,_>'.
