digitalmars.D.learn - Cyclic dependency error

My program compiled, but when I ran it I got this error message:

object.Error src/rt/minfo.d(371): Cyclic dependency between 
module variable and main
variable* ->
misc ->
main* ->
variable*


I take it that the -> represents a dependency from the module on 
that line, to the module on the line below. My question is what 
do the asterisks represent?

The asterisks represent modules with module ctors/dtors. So misc is an intermediate step, but has no module ctor/dtor. A cycle between a module with a ctor and itself is OK, as long as it only goes through such import paths. -Steve

See https://dlang.org/spec/module.html#order_of_static_ctor for options on how to handle cycles other than rewriting.
