Unquoted string "say" may clash with future reserved word

[topbanana]

Hello, So I have two issues: 1: script won't execute on the bash command line unless I prefix it with "perl" , and 2: "Unquoted string "say" may clash with future reserved word" Please see below. I am running cygwin on Windows7 with perl installed. The script is called hello.pl. It has execute permissions. It has #!/usr/bin/perl at the top. It uses the "say" command. I'm running 5.14 The script won't run unless I call it with "perl". Why is this? Also, the "say" command doesn't work. Appreciate any help in advance. Thanks J

~/perl
J-PC:J >which perl
/usr/bin/perl
~/perl
J-PC:J >ls -l hello.pl
-rwxr--r-- 1 J None 44 Feb 26 15:22 hello.pl
~/perl
J-PC:J >cat hello.pl
#!/usr/bin/perl

use warnings;
say "hello";
~/perl
J-PC:J >. hello.pl
-bash: use: command not found
-bash: say: command not found
~/perl
J-PC:J >perl hello.pl
Unquoted string "say" may clash with future reserved word at hello.pl 
+line 4.
String found where operator expected at hello.pl line 4, near "say "he
+llo""
        (Do you need to predeclare say?)
syntax error at hello.pl line 4, near "say "hello""
Execution of hello.pl aborted due to compilation errors.
~/perl
J-PC:J >perl -v

This is perl 5, version 14, subversion 2 (v5.14.2) built for cygwin-th
+read-multi-64int

Additional information: Even changing "say" to "print", and trying to run by using "." I get no joy:

~/perl
J-PC:J >cat hello.pl
#!/usr/bin/perl

use warnings;
print "hello";
~/perl
J-PC:J >. hello.pl
-bash: use: command not found
