...we can provide a list too in split function.
Sorry, no. split operates on a single string (a scalar), but not on a list:
13:57 >perl -wE " $s = q[abc]; $t = q[mno]; say for split(//, $s, $t);
+ "
Argument "mno" isn't numeric in split at -e line 1.
a
b
c
14:06 >perl -wE " $s = q[abc]; $t = q[mno]; say for split(//, ($s, $t)
+); "
Useless use of a variable in void context at -e line 1.
m
n
o
14:06 >perl -wE " @u = (q[abc], q[mno]); say for split(//, @u); "
2
14:06 >
The docs however mention EXPR ... which I assumed to be a scalar.
Yes, your original assumption was correct. But split returns a list, which is why the output of split can be the subject of a foreach or a map.
Hope that helps,

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
