Add a module declaration to your source file. For example:
echo 'module abc; import std; void main(){writefln(__MODULE__);}' | dmd
-run -
Output:
abc
`__stdin` is used as a placeholder when no module declaration is
present, and dmd doesn't know the filename (which is what it would
normally have used for the module name in this case).
