I've been using F# for a while. The main benefit I've had from having access to the source is being able to figure out exactly how things work. A _lot_ of F#'s "magic" is in libraries written in F#, and the source to those is very clear and easy to navigate and figure out. The compiler is of course more complex, but the few times I've wanted to figure out a specific issue in the compiler that the F# language spec didn't explain, it's come in handy.
This also holds true for the .NET Framework class libraries. Visual Studio can automatically step into the source while debugging. This has saved me tons of time.
