The problem is the state feature is turned off inside utf8::all... somehow. I can reduce this down to a weird interaction between "use v5.10" and something in Method::Signatures. # "Hello" use v5.10; say "Hello"; # "Hello" use v5.10; use Method::Signatures; say "Hello"; # Error use Method::Signatures; use v5.10; say "Hello"; String found where operator expected at /Users/schwern/tmp/test.pl line 4, near "say "Hello"" (Do you need to predeclare say?) syntax error at /Users/schwern/tmp/test.pl line 4, near "say "Hello"" Execution of /Users/schwern/tmp/test.pl aborted due to compilation errors. The problem is the 5.10 features aren't being turned on. It's specific to the "use v5.10" syntax because "use feature ':5.10'" works. And it's strange that the order of operations matters. I wonder if something MS is doing is corrupting %^H and/or tickling a bug. MooseX::Method::Signatures doesn't have this problem, which suggests, but does not rule out, a Devel::Declare problem.

It's something about Lexical::SealRequireHints. Remove that and it all works.

This works on 5.10.1.

    use v5.10;
    use Lexical::SealRequireHints;
    say "Hello";

This errors, the say feature is not loaded.

    # String found where operator expected at /Users/schwern/tmp/test.pl line 3, near "say "Hello""
    #    (Do you need to predeclare say?)
    # syntax error at /Users/schwern/tmp/test.pl line 3, near "say "Hello""
    # Execution of /Users/schwern/tmp/test.pl aborted due to compilation errors.

    use Lexical::SealRequireHints;
    use v5.10;
    say "Hello";

But the plot thickens! This works.

    use Lexical::SealRequireHints;
    use feature ':5.10';
    say "Hello";
