i d ask me one other .. asking where 'the specific' s place is , to code it
there , where it belongs

Greg, for example, puts a lot of value in being able to use the same code

im a poor invalid-rent in swiss assed , tech++ privateer
to me only newest versions count ( preferabily containing feature addments )

to me as pro bash coder ( i sitted and learned and teachen further by
interactive computer chats ( mostly irc ) ) for years
.. to me , knowing all the bugs bash has over some time , makes me have big
anti reasons to use old bashes

i mean its one to support old
but , why does that old exist
redhat 5 6 7
they cant update ? or use extra , old softwre , to exploit flaws in sw
.. to support such .. no me man , not for me

i mean i got clauses here and there , in my coding freelance ing , one is
'pref. updated debian to run' - that is debian all public short tree s ,
not just useless 'stable' - and i d put it on as sometimes

i try to say , .. stuff is incomplete , and if fixes dont come , just as no
good as always it is
just as ppl support 4.2 i 'only newest'

greg did great examples btw

This was the entire rationale for the compatibility mode in the first

Backwards compatibility is important, and I put a lot of effort into it.

it s a vital work for you , ye
i can just say , changing quotes to be interpreted is imo vital too :p i
mean done correctly better now than before

when , you have smth , like sh or bash , or non computer stuff
it takes , its known-to-be , material-beeing
which will in time need changes to be done to it

hm hm , greets , x
