Is this an F# quotations bug?
- by ControlFlow
[<ReflectedDefinition>]
let rec x = (fun() -> x + "abc") ()
The sample code with the recursive value above produces the following F# compiler error:
error FS0432: [<ReflectedDefinition>] terms cannot contain uses of the prefix splice operator '%'
I can't see any slicing operator usage in the code above, looks like a bug... :)
Looks like this is the problem with the quotation via ReflectedDefinitionAttribute only, normal quotation works well:
let quotation =
<@ let rec x = (fun() -> x + "abc") () in x @>
produces expected result with the hidden Lazy.create and Lazy.force usages:
val quotation : Quotations.Expr<string> =
LetRecursive
([(x, Lambda (unitVar,
Application
(Lambda (unitVar0,
Call (None,
String op_Addition[String,String,String](String, String),
[Call (None,
String Force[String](Lazy`1[System.String]),
[x]), Value ("abc")])),
Value (<null>)))),
(x, Call (None, Lazy`1[String] Create[String](FSharpFunc`2[Unit,String]), [x])),
(x, Call (None, String Force[String](Lazy`1[String]), [x]))], x)
So the question is: is this an F# compiler bug or not?
