Enum AstBlockItem

pub enum AstBlockItem {
    Declaration(AstDeclaration),
    Statement(AstStatement),
}

An item in a block can be a statement or a declaration.

In C, declarations (even with initializers) are not statements. E.g. this is invalid C code (but is valid C++):

if (condition)
    int a = 1;

So we treat declarations separately from statements. A declaration with an initializer expression will be translated into IR so that the initializer expression becomes an assignment.

Note: Type alias (typedef) declarations do not appear in our AST. The Parser handles them during parsing but has no need to construct them in the AST.
