$builtin_expando(<expando name>)

• If the <expando name> argument is omitted the empty string is returned.
• If the inline expando <expando name> does not exist, the empty string is returned.
• This function returns the value that would be returned by the “inline expando” $<expando name>.

The inline expandos ($A, $B, $C, etc) can be overridden by user variables (eg, /assign A testing). If you need to call the underline inline expando and to be sure that you won't be thwarted by an assign alias, then you can call this function to invoke the inline expando.

$builtin_expando(N)     returns your current nickname
$builtin_expando(C)     returns the current channel of the current window
