Subject: suggestion for possible performance enhancement

after seeing the speedup document, i think minor performance enhancement might be achieved by using Data::Alias in subs to access the arguments, or at the very least replace the overly misused idiom 'my $self = shift' with 'my ($self) = @_' to avoid unecessary modifications to the parameter array (@_).

Data::Alias requires 5.8.9 or later on Win32 (and AIX), so I don't want to use it. Is my ($self) = @_; really faster than my $self = shift; ? I haven't seen any benchmark that shows that. I'll have a look at it. Thanks. -- mirod
