in thread Moose and File::Temp

You may have some difficulty with isa => 'FileHandle' because while FileHandle is a core Perl module, Moose uses the type constraint string "FileHandle" to refer to unblessed Perl file handles - i.e. not objects created by the FileHandle package.

open my $fh , "<", "temp.txt"; $self->fh($fh); while (<$fh>) { print $_; }
perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'

    So it is impossible to use  while(<$self->{IamAfileHandleAttribute}>) { ... } > to read a file, outside my constructor. I guess I will have to do:
    my $temp_fh = $self->{IamAfileHandleAttribute}; while (<$temp_fh>) { ... }
      So it is impossible to use while(<$self->{IamAfileHandleAttribute}>) { ... } > to read a file
      no, it's not really impossible. you can just use readline instead of the diamond operator.
      while (readline $self->{IamAfileHandleAttribute}) {

[moritz]: seems there's a size limit for hostenum, and the error message just sucks
[vrk]: None, other than the location of the error: auto/NetAddr/IP/ _splitref.al
[vrk]: Aha, there's a reference to "bug report 82719" in NetAddr/IP.pm's sub _splitref.
[moritz]: wow, that's their idea of an "improved error message"
[moritz]: how about "This network is too large to enumerate all host addresses." or so?
[vrk]: Well, there's a call to notcontiguous() before the error, whose description is "counts the bit positions remaining in the mask when the rightmost '0's are removed"
[vrk]: Clear as mud!
