Because despite the name
@list you're in fact assigning it a single element which is precisely the string
"'Ashok Hello'", that is: without the external double quotes, but
with the internal single ones. That is precisely the difference between
q() and
qw(): the former returns non interpolated strings, and when used with
"'" (single quotes) as a delimiter
"q" become redundant, while
the latter returns a list of (non interpolated) "words"
1, splitting on whitespace.
1 Notice the double quotes - I mean that they're not required to match
/^\w+$/.
