Intrascheme

Intrascheme is a term used in multiple domains with no single universally accepted definition. In computing contexts it sometimes denotes processes, data, or communications that remain entirely within a single Scheme-based environment or framework, as opposed to those that cross linguistic, runtime, or system boundaries. Because Scheme refers to a family of Lisp dialects, intrascheme typically implies interactions confined to the Scheme runtime, its modules, or its compiler and interpreter, without invoking foreign languages or external services. In practice, the exact meaning is context-dependent; some discussions use it to describe internal program analysis, transformations, or optimizations performed within the Scheme ecosystem, such as macro expansion, module linking, or in-memory representation changes that do not reach outside the language boundary.

In other fields, the term may appear in discussions about organizational or methodological schemas, where "intra-" indicates within a single framework. Here, intrascheme would similarly mean operations or models defined within one scheme or design, rather than between multiple schemes. However, this usage is rare and not standardized.

Because the term is not widely standardized, readers should refer to the specific source or community where it appears to determine the intended scope. See also Scheme (programming language), modules, macros, and intra-language design.
