modulewhile
Modulewhile is a hypothetical programming construct that combines modular scope with a while loop. It is designed to execute an iterative process while keeping the loop’s internal state contained within a module boundary, exposing a fixed interface to the outer program. In languages or proposals that support modular scoping, a modulewhile loop uses a private module to store state that is not directly accessible from the surrounding code, helping to prevent unintended interactions.
The main purpose of modulewhile is to improve encapsulation, reusability, and safe composition of looping logic.
Semantics of modulewhile vary by language, but common ideas include: a module is instantiated at the start
Syntax, in proposed forms, resembles a standard while loop but scoped within a module. A typical form
Notes and history: modulewhile remains primarily a design concept discussed in language-design literature, not a widely
