A lot of src/string string_ operations are capable of dealing with NULL strings currently [1]. *But* that's AFAIK specificied nowhere, and might just be an accident, i.e. an extra (unneeded/unwanted) check for A NULL argument. A consistent behavior would make all these things just errors, the same as we got with the Null PMC, which has been created for this very reason - the same as a SEGV in C, when accessing a NULL ptr. leo [1] null S0 # this is not '' length I0, S0 # 0 concat S1, S0, "foo" # "foo"
