No, it is still

Rejected by upstream, citing minimalness.
A related fix for
eval "alias $(alias 'a|b|c=d'; alias)"
executing code was accepted
(well "will look into it"ed, where "it" is my complete patch? idk), tho.
This makes dash, as you note, incompatible with ksh93 and bash,

Indeed; escaping of any kind (quoting or backslash) disables alias
expansion. What's even more fun is that if you do
alias "a'b=c" "ls=cd"
then alias
Package: dash
Version: 0.5.7-4
Severity: wishlist
With dash, one can defined an alias with a backslash:
$ alias '\mv=echo ab'
$ alias
\mv='echo ab'
but it can't be used:
$ \mv
mv: missing file operand
Try 'mv --help' for more information.
So, it would be better to return an error like with
8 matches
