mimick namespace in bash?

[Peng Yu]

Hi,

It seems that hash and alias does not support "/" in the command. Is it so?

If it does, it can be used to mimick namespace. Should this feature be
considered to be added to bash?

$ builtin hash -p /usr/local/opt/coreutils/libexec/gnubin/ls my/ls
$ my/ls
-bash: my/ls: No such file or directory

$ alias my/ls=/usr/local/opt/coreutils/libexec/gnubin/ls
-bash: alias: `my/ls': invalid alias name
