kex module documentation has:
3.4. setbflag(flag [, branch])
flag - the index of the branch flag to be set. Can be integer or
pseudo-variable with integer value.
are quotes "" always required?
setbflag(1);
does not give an error (or at least i cannot find one from among all
those debug messages that seem to be on by default).
if quotes are required, is it sure that if string is an int, it will be
evaluated when the script is processed and not when script is run?

The quotes are optional. I was curious about this too and checked that both
variants (with and without quotes) work correctly.

I am not sure about this, I guess this is a question for Daniel.

this is too arbitrary. the syntax needs to be consistent. i would
prefer int arg without quotes and string arg with quotes. if arg is
pseudo variable, it should be written without quotes, because it is a
VARIABLE.

I didn't implement it this way, I was surprised that setbflag without quotes
didn't produce an error and that's why I gave it a try.
I thought that all parameters of module functions had to be quoted, but
apparently this is not needed anymore. It was probably changed when ser and
kamailio module interfaces were merged.

if i write
isbflagset("15")
is "15" evaluated to the bit during compilation of the script or is
"15"
processed like a string that contains pseudo variables?
Even in SR I cannot see the way to specify the type of

in my opinion, in the above case, because the function requires an int
argument, only these two should be accepted:
isbflagset(int)
isbflagset($pv)
both without quotes and $pv has to contain an int value.

why would you need to be able to specify it? if i write
isbflagset(15)
the function will get an int value. if that is not correct, then you
get an error whet you try to execute that function. the same thing as
if i write
isbflagset($pv)
compiler cannot tell, if value of $pv is int or string.

All K modules' exported function are built with this architecture in

in that case, isbflagset (or other functions) should only accept string
values. it is confusing if some of them accept also ints.
but in the long run, we could allow int and pv arguments without quotes.
