Specification
https://github.com/gpuweb/gpuweb/pull/6291


Summary
WGSL language feature for reinterpreting data in variables. The feature allows 
developers to divide a single uniform, storage, or workgroup variable into 
multiple logical variables. It also allows the type of the data in the variable 
to be interpreted as multiple types within the program.


Blink component
Blink>WebGPU


Web Feature ID
webgpu


Motivation
This features adds a new opaque type for use with storage and uniform buffers 
and workgroup variables. It allows the data in those variables to be 
reinterpreted as other types. This is useful for both type-punning data and 
logically sub-dividing a variable into multiple parts. For ease-of-use and 
safety, the opaque type can only be operated on by new built-in functions. The 
reinterpretation can only occur on the opaque type. This maintains flexibility, 
but reduces implementation complexity.

Anticipated spec changes

Open questions about a feature may be a source of future web compat or interop 
issues. Please list open issues (eg links to known github issues in the project 
for the feature specification) whose resolution may introduce web 
compat/interop risk (eg, changing to naming or structure of the API in a 
non-backward-compatible way).
