Moves type name around when writing constrained type defintions

[vsinha]

Issue created from fantomas-online

Code

type 'a t when 'a :> IDisposable = T of 'a option

Error

Fantomas was able to format the code but the result appears to be invalid F# code.
Please open an issue.

Formatted result:

type 'a when 'a :> IDisposable t = T of 'a option

Problem description

The t moves to after the IDisposable, which leaves us with invalid F# code. The pre-formatted code builds successfully.

Extra information

• The formatted result breaks by code.
• The formatted result gives compiler warnings.
• I or my company would be willing to help fix this.
