### Minor changes to the library {#minor_library_changes}

#### go/types

The `Var.Kind` method returns an enumeration of type `VarKind` that
classifies the variable (package-level, local, receiver, parameter,
result, or struct field). See issue #70250.

Callers of `NewVar` or `NewParam` are encouraged to call `Var.SetKind`

Within the Go file, C's struct field names that are keywords in Go
can be accessed by prefixing them with an underscore: if x points at a C
struct with a field named "type", x._type accesses the field.
C struct fields that cannot be expressed in Go, such as bit fields
or misaligned data, are omitted in the Go struct, replaced by
appropriate padding to reach the next field or the end of the struct.
