Issue ID: 13643
Summary: memoize lazy parameter evaluation
Product: D
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P1
Component: DMD
Assignee: [email protected]
Reporter: [email protected]
Currently D's lazy parameters use call-by-name, i.e. the expression is
evaluated whenever referenced. Historically lazy refers to call-by-need
evaluation where the result is cached on first use.

We could at least do it for pure expressions that are referenced multiple
times.
