-fdefer-type-errors and -fdefer-typed-holes flag do not perform their roles
with -fdefer-type-errors
flag\\
Prelude > let f = [True | x <- [_,_]]
raise two warning. Good!.\\
Prelude > f
\\
[True, True]
\\
With this function \\
Prelude> let f' = [True | x <- [_, _]] in f'
\\
GHCi raise two errors.
It is not clear!
idem with -fdefer-typed-holes
flag\\
If you compile, there is a warning and of course no result and after linking an error is raise. This situation is not clear for me.\\
Logically it should have a result.\\
logically the function f
and the function f'
send a result.\\
Typed Holes worsens in this case
