Yes, this is an inconsistency that I acknowledge.

This is an option, but that would require all callers of this function to pass 
IMSI (`g_pars.imsi`) implicitly. Unlike with TMSI, I hardly see a scenario in 
which one would want to pass anything else than `g_pars.imsi`. So by doing that 
we would loose more than win.

As a compromis, I propose the following:

```
function f_expect_paging_tmsi(template OCT4 tmsi := *) { ... }
function f_expect_paging() {
    f_expect_paging_tmsi(g_pars.tmsi);
}
```

This way we would be using `g_pars.imsi` and `g_pars.tmsi` by default, but at 
the same time allow the API user to overwrite the TMSI expectations.
