Subject: proc return statement

I am having problems returning a value from a proc object:

@@mappings.each{ |hsh|
        begin
          if( hsh['type'] == c['type'] ) then
            eval( "comp=#{hsh['template']}" )
            hsh.each_key{ |key|
              m = proc { @@ignore.each{ |i| return true if( key == i ) } 
}.call
             puts m;
            }
            has_mapping = true;
          end
        rescue; raise "Unable to evaluate passed in expression: 
#{hsh['template']}"; end
        break if( has_mapping ); }

It is at the line:    m = proc { @@ignore.each{ |i| return true if( key 
== i ) } }.call
that I am having the problem. I want "m" to be true, but instead it 
leaves the calling function.

I have modified the line to be:

m = nil;
proc { @@ignore.each{ |i| m=true if( key == i ) } }.call

but I was just wondering if I could return a value w/o having to leave 
the outer function.
