Clang at least does the type deduction right. You can convince yourself on the
command line by running it with "-fsyntax-only -Xclang -ast-dump".

Tough. The c-index that we use doesn't contain that information apparently. At
least "c-index-test -index-file" on the example code spits out
[startedTranslationUnit]

As you can see the calls at 6:4 and 7:4 just contain a reference to the
function template foo:1:27 (the numbers are line:column). One would think that
the magic string tells us something alas another line
foo(1.0);
produces the same magic string:
[indexEntityReference]: kind: function-template | name: foo | USR:
c:@FT@>1#Tfoo#t0.0#v# | lang: C++ | cursor: DeclRefExpr=foo:1:27 | loc: 8:4 |
<parent>:: kind: function | name: main | USR: c:@F@main# | lang: C | container:
