See cod below :

module linkfailclass;

class A {
    A[string] foobar;
}

module linkfailuse;

import linkfailclass;

void main() {
    auto a = new A();

    foreach(key; a.foobar.byKey()) {

    }
}

Then compile :

dmd -c linkfailclass.d dmd -c linkfailuse.d

dmd -oflinkfail linkfailclass.o linkfailuse.o
linkfailuse.o: In function `_Dmain':
linkfailuse.d:(.text._Dmain+0x20): undefined reference to
`_D6object45__T16AssociativeArrayTAyaTC13linkfailclass1AZ16AssociativeArray5byKeyMFNdZS6object45__T16AssociativeArrayTAyaTC13linkfailclass1AZ16AssociativeArray5byKeyM6Result'
linkfailuse.d:(.text._Dmain+0x29): undefined reference to
`_D6object45__T16AssociativeArrayTAyaTC13linkfailclass1AZ16AssociativeArray5Range5emptyMxFNdZb'

Template is instantiated in linkfailclass so linkfailuse assume it is in it. But some members of the template are not instanciated because not used in linkfailclass. linkfailuse assume they are.
