pointer_composite_access

Check navigator.gpu?.wgslLanguageFeatures?.has('pointer_composite_access') before choosing a shader that uses this language feature. It is available automatically when supported; requires pointer_composite_access; documents the dependency and rejects the shader on unsupported implementations. This language token is not a requiredFeatures entry for requestDevice(); any additional device requirements are described below.

When p points to a structure, p.member refers to that member of the pointed-to structure. For a pointer to an array, p[i] accesses its selected element. These forms provide the same kind of memory access as (*p).member and (*p)[i], with less punctuation in pointer-heavy code.

This helps generated shaders and reusable compute helpers remain readable when they traverse nested arrays and structures. It is a syntax convenience for an existing memory view, not a data copy or a new allocation.

It does not by itself relax which pointers can be passed to functions; that is unrestricted_pointer_parameters. Access modes and bounds rules still apply. For implementations without this syntax, generate the equivalent expression with an explicit dereference and parentheses.
