>From the grammar documentation:

Decl:
    StorageClasses(opt) BasicType Declarator FunctionBody

DMD rejects the following code:

void function() foo {};

and accepts the following:

void function() foo = {};

According to the grammar spec, the latter should be parsed as a variable
declaration whose type is "void function()", with a name of "foo" and an empty
struct initializer. (By the way, the grammar does not allow empty struct
initializers). This should not pass semantic analysis because a struct literal
is not of type void function().
