Comment (by vanto):

 Hello goldfire,\\

 yes, I agree with you. It is not a bug.
 However this behavior is irrational.
 Reason has disappeared, good sense no longer exists.\\
 See ticket #13557.\\
 In this ticket simonpj said " I think this is correct behaviour".\\
 Yes simonpj, this behavior is correct since you coded it as well!
 The compiler is stupid, where is the good sense? \\
 It is because this good sense did not appear in GHC 7.6.3 that this
 continues.
 The compiler would have a better behavior, with more good sense, if
 "typed holes" was set off as of launch, I think.\\
 If you want to comment before I close the ticket, thank you.
 Soon I open a new feature request ticket to repeat this.
