With
print(list(A="a",B="b"))
it displays
$A
[1] "a"
$B
[1] "b"
I would like to add a common prefix to all the list tags after the $.
Pasting the prefix to the "names" does not work (appear after the $).
For example if the prefix would be "P", it should display:
P$A
[1] "a"
P$B
[1] "b"

I have a data frame with named columns and I would like to know if it is
possible to retrieve a column name once selected:
print(colnames(df)) # assumes to print "col1" "col2"
print.name(df$col1) # would like to print "col1"
print.name(df$col2) # would like to print "col2"
So what the print.n
