I wonder if it would be worthwhile provide "official" mechanisms to do what they're doing in the typemap, so maybe:

 T_STR_LEN
    PREINIT:
        STRLEN ${var}Len;
    EXPAND:
        $var, ${var}Len
    INPUT:
    {
        SV * TmpSV = $arg;
        $var = ($type) SvPV( TmpSV , ${var}Len);
    };

I haven't tried to implement this yet.
