$ echo -e 'a,b,c\nd,e,f'
a,b,c
d,e,f
$ echo -e 'a,b,c\nd,e,f' | opy -t csv '[T]'
{0: ['a', 'b', 'c'], 1: ['d', 'e', 'f']}
### print an element ###
$ echo -e 'a,b,c\nd,e,f' | opy -t csv '[T[1][1]]' 
e

$ echo -e 'a,b,"c\nd",e,f'
a,b,"c                             <- this is **one-line** csv data ( "c\nd" is an element.)
