A *one-index* constructor tag
Type of the tags associated with each constructor possibility or superclass selector
Tags are allocated from here for real constructors or for superclass selectors
The number of value arguments that can be applied to a value before it does "real work". So: fib 100 has arity 0 x -> fib x has arity 1 See also Note [Definition of arity] in GHC.Core.Opt.Arity
The number of arguments that a join point takes. Unlike the arity of a function, this is a purely syntactic property and is fixed when the join point is created (or converted from a value). Both type and value arguments are counted.
type FullArgCount = Int Source #
FullArgCount is the number of type or value arguments in an application, or the number of type or value binders in a lambda. Note: it includes both type and value arguments!

Overlappable SourceText | Silently ignore this instance if you find a more specific one that matches the constraint you are trying to resolve Example: constraint (Foo [Int]) instance Foo [Int] instance {--} Foo [a] Since the second instance has the Overlappable flag, the first instance will be chosen (otherwise its ambiguous which to choose) |
Overlapping SourceText | Silently ignore any more general instances that may be used to solve the constraint. Example: constraint (Foo [Int]) instance {--} Foo [Int] instance Foo [a] Since the first instance has the Overlapping flag, the second---more general---instance will be ignored (otherwise it is ambiguous which to choose) |
Overlaps SourceText | Equivalent to having both |
Incoherent SourceText | Behave like Overlappable and Overlapping, and in addition pick an arbitrary one if there are multiple matching candidates, and don't worry about later instantiation Example: constraint (Foo [b])

The OneShotInfo type
data OneShotInfo Source #
If the Id
is a lambda-bound variable then it may have lambda-bound
variable info. Sometimes we know whether the lambda binding this variable
is a "one-shot" lambda; that is, whether it is applied at most once.
This information may be useful in optimisation, as computations may safely be floated inside such a lambda without risk of duplicating work.
See also Note [OneShotInfo overview] above.
