I've never used ksh88. so I do not know the intersection with ksh93. but my
experience so far is
that it seems easier to port a

that (restoring consistency with ksh93/bash) would be good, I believe.
subtle incompatibilities in behaviour (as opposed to syntax differences
causing manifest syntax errors) are the most painful when porting
scripts between shells in my experience, especially because they might
be missed during

ok, I got it that this seems to be the idea here, but
1.
what about
typeset -i x=0; x+=1; echo $x # → 1 (as in ksh/bash/zsh)
if += categorically does string concat no matter what, should this not
Thanks for the extensive debugging/comparing work.
I think I’ll change mksh to match AT ksh93 for consistency and will
try to hunt down the cause for the difference.

Public bug reported:
consider
typeset -i x=0; x+=1; echo $x # → 1 (as in ksh/bash/zsh)
but
typeset -i x=1; x+=1; echo $x # → 11 (rather than 2 as in the other
shells)
I believe mksh should honour the integer declaration and interpret `+='
accordingly. currently, it does not even consistently
