Is it possible to get the exact variable type with range/limits when entering '?'/'TAB'

[precla]

Having the following:

interface <ifname:string interface()>("Interface name") {
    ip <ipaddr:ipv4addr>("IPv4 address"), set_interface_ip();
    ipv6 <ipaddr:ipv6addr>("IPv6 address"), set_interface_ipv6();
    mtu <size:uint16 range[68:65535]>("MTU size"), set_mtu();
}

network(config)>interface wlan0 mtu ?
  <size>                MTU size

Instead I'd like to see size[68:65535], like this:

network(config)>interface wlan0 mtu ?
  <size[68:65535]>                MTU size

Same for strings:

hostname("Change hostname") {
    <hostname:string length[8:32]>("hostname"), set_hostname();
}

network(config)>hostname ?
  <hostname>            hostname  

Having <hostname[8:32]> or similar would be nice. Or a bit more info, since in this cases i proposed, neither command's help tells us if it is a string or integer.

I also know that there are regex possibilities and combinations. So I'm not sure if this is doable in a sane and simple way.
