sort

This is a list of sorts (i.e. static types) that are the basis for the static language of ATS; ATS is a layered system: sorts are used to classify static terms, and static terms are used to classify dynamic terms.

Ground Sorts

These are sorts that can be viewed as counterparts of types in C. Combined with other sorts and features of ATS, this allows us to prove at compile-time propositions made involving C types (or more complex types involving these ground sorts). This means also that every ground sort has an analogous dynamic type of the sort t@ype: int, bool char, addr

Other sorts

cls, eff, prop, tkind (alias tk), t@ype, type, view, viewt@ype, viewtype.

eff 's are function effects. The [internal type](Internal types) is S2Eeff.

Views are linear resources that signify a certain type is accessible from an associated variable. At-views, or @ views, are a special case of views which signify that a certain type is dereferencable at a specified memory location; they are used with pointers.

tkind is like 'type'; it is algebraic (that is, not involving quantifiers). The plan is to use tkind to support a more flexible/powerful way of template instantiation.

types is the sort of variadic arguments. See variadic.dats
