All declarations with the same signature must refer to the same 
function. Or, in other words, only one of them can have a 
function body, and that body will be used for all calls that 
match any of the equivalent declarations.

Redundant declarations like this are actually already allowed in 
D; there just isn't any particular reason you'd want to use them.
