Thanks, merged:

I removed the explicit conversion in val_compare(), moved as_path_filter()
changes to a separate patch and changed it to use struct f_val (similar
functions for *lists also use that).

Already added typechecks for function call, which fixes issue when '[]'
is passed as prefix set arg:

Will add constant promotion to FI_EQ to handle issue comparing literal '[]'
with prefix set variable.
