I'm not sure exactly where it is in the docs but that's perfectly
normal.
Any declaration with initialization of a struct is turned into a
construction call if it can. If not, it tries to treat it as a
struct literal.
I guess this is as close as it comes:
https://dlang.org/spec/struct.html#struct-constructor
"Struct constructors are used to initialize an instance of a
struct when a more complex construction is needed than is allowed
by static initialization or a struct literal. "
Which sends you back up here:
https://dlang.org/spec/struct.html#static_struct_init
showing the = syntax.
opAssign is only used AFTER the struct has already been declared.
