OR some like to write it like so:

that is a poor idea. setting $" isn't needed to do a simple join.
but what no one has said is a more direct way to do this. you need map
and join but it is much cleaner and easier to understand and without the
bracket or precedence issues:
my @fruits = qw( apple pear banana ) ;
print join '', map "[$_]", @fruits ;
now you can see each element surrounded by [] and then joined into one
string for printing.
you don't even need the join if you are just printing it but i put it
there so you can use the same concept if you are going to save the string.
print map "[$_]", @fruits ;
that is very clear what is going on and should be the code used to print
such a string. use the join '' form if you need to keep the string.
