No, the point of the FTProps object is to emulate Python keyword arguments.
I believe this is called "the named parameters idiom" in C++, if you replace
this:

>     FTProps p("cat.jpg", "image/jpeg", 5000);

with something like this:

account.createFileTransfer("foo at bar.com", "cat.jpg", "image/jpeg", 5000,
    FTProps()
        .lastModificationTime(47547)
	.description("my cat")
	.hash("crc32", "deadbeef"));

This also allows adding more properties later, if needed (as long as the
FTProps struct has a mPriv).
