Oh, sorry. The rule can be written line this:

rule my-tag ( name : type ? : property-set )
{
if $(type) = EXE && [ $(property-set).get <variant> ] = debug
{
return [ virtual-target.apply-suffix $(name)_d : $(type)
: $(property-set) ] ;
}
}

If you add <tag>@mymodule.my-tag to properties, then all executable files will 
get "_d" added in debug variant. The above rule returns something only for 
EXE/debug combination, in all the other cases nothings is returned and 
default name is used.

Reproduces for me. Fix is not committed, thanks for spotting.
