You're right that UFCS is not root cause; i've updated the title.
indeed, if we remove 'void foo' entirely it errors with "Error: no property
'foo' for type 'A'" instead of erroring with what it should: 
main.d(13): Error: 'writeln' is not defined, perhaps you need to import
std.stdio; ?
main.d(22): Error: template instance main.A.opDispatch!("foo") error
instantiating
