NAME

       Eval::TypeTiny - utility to evaluate a string of Perl code in a clean environment

STATUS

       This module is considered part of Type-Tiny's internals. It is not covered by the Type-
       Tiny stability policy.

DESCRIPTION

       This module is used by Type::Tiny to compile coderefs from strings of Perl code, and
       hashrefs of variables to close over.

   Functions
       This module exports one function, which works much like the similarly named function from
       Eval::Closure:

       "eval_closure(source => $source, environment => \%env, %opt)"

   Constants
       The following constants may be exported, but are not by default.

       "HAS_LEXICAL_SUBS"
           Boolean indicating whether Eval::TypeTiny has support for lexical subs.  (This feature
           requires Perl 5.18.)

       "HAS_LEXICAL_VARS"
           Don't worry; closing over lexical variables in the closures is always supported!
           However, if this constant is true, it means that Devel::LexAlias is available, which
           makes them slightly faster than the fallback solution which uses tied variables. (This
           only makes any difference when the "alias => 1" option is used.)

EVALUATION ENVIRONMENT

       The evaluation is performed in the presence of strict, but the absence of warnings. (This
       is different to Eval::Closure which enables warnings for compiled closures.)

       The feature pragma is not active in the evaluation environment, so the following will not
       work:

          use feature qw(say);
          use Eval::TypeTiny qw(eval_closure);

          my $say_all = eval_closure(
             source => 'sub { say for @_ }',
          );
          $say_all->("Hello", "World");

       The feature pragma does not "carry over" into the stringy eval. It is of course possible
       to import pragmas into the evaluated string as part of the string itself:

          use Eval::TypeTiny qw(eval_closure);

          my $say_all = eval_closure(
             source => 'sub { use feature qw(say); say for @_ }',
          );
          $say_all->("Hello", "World");
