I have a module in which I want to use locale or use utf8 depending on a condition. Something like:

if( $locale)
  { use locale; }

elsif( $utf8 and $perl_version_ok) 
  { use utf8; }

if( $word=~ /^\w+$/) { ... }

Obviously the way \w matches is impacted by the locale/utf8 setting.

My problem is that use locale/utf8 is scoped to the enclosing block, hence the use pragma will not be in scope outside of the if block and \w will just match [a-zA-Z]. How could I get it to match what I want?

In addition I would need to have the locale/utf8 active in most of the module, so it might be difficult to find an enclosing block. This means also that I can't put the statements affected by the pragma in the block. This is not possible:

if( $locale)
  { use locale; 
    if( $word=~ /^\w+$/) { ... }
  }
elsif( $utf8 and $perl_version_ok) 
  { use utf8; 
    if( $word=~ /^\w+$/) { ... }
  }
