memory leaks

export p='$'
$p
cat Makefile | pwd | cat '-e' | wc -l > p 

----------------------------------------------------------
parsing

cat << $POKPO
ours: syntax error
bash: starts heredoc with $POKPO as delim 

<< $POP cat 
ours: takes cat as delim because $POP expands to nothing

env > $Q
should be ambigious redirect i guess (what an annoying case >_>)

----------------------------------------------------------
exit issue 

exit f f 
ours: displays both error msgs, wrong
exit '' 
ours: does not detect it as non numeric, takes atoi value as it is, wrong
