What does XNoMonomorphismRestriction
switch mean?
해결책
It turns off the Monomorphism restriction, which restricts values which are not defined using "function notation"¹ to have a non-polymorphic type.
¹ By "not using function notation" I mean that they're defined as foo = something
and not foo bar = something
, i.e. the definition does not contain explicit arguments.
