+### try to use per-field initialized const struct
+
+Use the `.field = ...,` initialization pattern instead for `var.field =
+...;`, especially if it means you can have the variable be declared 'const'
+that way.
+
+Example, instead of:
+```cpp
+WGPUTextureViewDescriptor view_desc = {};
+view_desc.format = g_format;
+view_desc.dimension = WGPUTextureViewDimension_2D;
+view_desc.mipLevelCount = 1;
+view_desc.arrayLayerCount = 1;
+```
+
+use:
+```cpp
+const WGPUTextureViewDescriptor view_desc = {
+  .format = g_format,
+  .dimension = WGPUTextureViewDimension_2D,
+  .mipLevelCount = 1,
+  .arrayLayerCount = 1,
+};
+```
+
+Make sure the `.field = ...,` initialization pattern is compatible with the compiler / c++ version used.

 ### vertical space
 
 keep the code compact vertically. That includes shader code, too.
