withConnection ambiguity

[LennysLounge]

The method withConnection is ambiguous if called like this:

Object value = sql2o.withConnection((con, obj) -> methodThatReturnsAValue(con));

Because the lambda could both return a void and an object the compiler doesnt know which version of withConnection to use.

The workaround is to explicitly call the return (or not) like this:

Object value = sql2o.withConnection((con, obj) -> {
    return methodThatReturnsAValue(con)
});

Sadly the assignment to the variable is not enough for the compiler to notice.

It would be really nice if it were possible to call it in an unambiguous way.
