in reply to Counting the number of replaces

I noticed that I had an incorrect superstition about using <I>, namely the brackets, in the left side of s///, as I thought it was normally replaced by reading from a filehandle. It seems to work here, though, so I wonder why I believed that....

    Because Perl is rather context-sensitive and uses <I> to mean that in other contexts? In the code: 
    while (<I>) {
  s/<I>/<italic>/g;
}

    the first <I> reads from a filehandle and the second is literal text to replace. Fun, isn't it? :)
