A mold is a data type in hoon.
Raw values may be type-cast to a mold, and molds can also be called as functions to coerce a value to its type (“molding”, “clamming”).
Three kinds of types:
- Atoms: values with auras.
- Molds: structures. Think of cells, lists, and sets.
- Marks: file types. Compare to conventional files distinguished by extension and definite internal structure.
Molds are actually gates. They operate on a value and coerce it into a certain structure. it’s a function from noun to noun.
