The concatenation operator supplies the context. Many operators supply
a scalar context, e.g
@a = "Hello Sailor;
$, = ' ';
print @a; # prints Hello Sailor
print @a + 1; # prints 3
print @a . 1; # prints 21
... but not all ...
print @a , 1; # prints Hello Sailor 1
BTW your join statement is equivalent to interpolating the array in a
string, so
$dialog=$top->Dialog(-title=>"Fertig", -text=>"Die Laufwerke\n@mapped\nwurden
erfolgreich angebunden",-buttons=>[qw/Ok/])->Show;
should look the same.

Perhaps you should compile your Perl with long doubles one of these
megaseconds.
