Relevance
An constructor argument is big if the sort of its type is bigger than
the sort of the data type. Only parameters (and maybe forced arguments)
are allowed to be big.
List : Set -> Set
nil : (A : Set) -> List A
A is big in constructor nil as the sort Set1 of its type Set
is bigger than the sort Set of the data type List.
A function argument can be relevant or irrelevant. See Agda.TypeChecking.Irrelevance.
Constructors
| Relevant | The argument is (possibly) relevant at compile-time. |
| NonStrict | The argument may never flow into evaluation position. Therefore, it is irrelevant at run-time. It is treated relevantly during equality checking. |
| Irrelevant | The argument is irrelevant at compile- and runtime. |
| Forced Big | The argument can be skipped during equality checking because its value is already determined by the type. If a constructor argument is big, it has to be regarded absent, otherwise we get into paradoxes. |
| UnusedArg | The polarity checker has determined that this argument
is unused in the definition. It can be skipped during
equality checking but should be mined for solutions
of meta-variables with relevance |
allRelevances :: [Relevance] Source #

irrelevantOrUnused :: Relevance -> Bool Source #

composeRelevance :: Relevance -> Relevance -> Relevance Source #

Irrelevant is dominant, Relevant is neutral.
inverseComposeRelevance :: Relevance -> Relevance -> Relevance Source #
inverseComposeRelevance r x returns the most irrelevant y
such that forall x, y we have
x `moreRelevant` (r `composeRelevance` y)

Function type domain
Similar to Arg, but we need to distinguish
an irrelevance annotation in a function domain
(the domain itself is not irrelevant!)
from an irrelevant argument.
Dom is used in Pi of internal syntax, in Context and Telescope.
Arg is used for actual arguments (Var, Con, Def etc.)
and in Abstract syntax and other situations.

Named arguments

so we give it another name here.
