Re: blessing a hash ref?

You've done well in simplifying the problem to a short set which duplicates the fault, but I get the impression you are sticking with print statements, and avoiding your debugger.

I would suggest tracing the code into the constructor, and exploring what $self contains just before the return. What does $tmpl contain after you return from the module?

P.S. You have 'use strict' in your main script, but not where you need it, in the module.

P.S. You have 'use strict' in your main script, but not where you need it, in the module. Once you declare 'use strict', anywhere, everything else is compiled under strict from that point on, to the end of the enclosing block. In this case, its to late, because the compilation of the module has already happened.

Fair point, but this is one many of us are guilty of -- and I think that is ok. First of, the Perl debugger isn't the most friendly tool in the world. Secondly, coming from many environments when attaching a debugger is not going to help much (say, an unfamilar OS such as Netware, web interfaces, or debugging the C code being loaded by a java JNI process), it is not to say that debug-by-print-statement is sin. It is this second reason that I have grown not to rely on debuggers and IDE's. Usually, I can't depend on them. I depend on runtime error checking most of the time -- and debug-by-print when things get hairy (which is not often). Plus sometimes using a debugger means your brain isn't really rapped around the code. I've been around folks who say "I need a debugger" -- but I've really learned to read code for flaws (even without prints). Using 10 different platforms and 3 or 4 different languages at work makes you do that. In many places, debuggers are heavy hammers to wield, and print statements serve their quick-and-dirty place. In more sophisticated ways, you can write less-dirty debugger modules that can route their output to log files and such `MyDebug::debug(-level => 4, -msg => "AllYourBase")`, which is something like what log4perl does, though I've never used it -- crafting my own simpler hooks was easy enough. Didn't Larry himself say he didn't use the debugger much? update: just reading random monks home nodes (I should be watching basketball -- go AirForce! Beat UNC!), I came across this interesting commentary on debuggers. It drives home a few of my points, or at least gives me the assurance that I am not alone.	[reply] [d/l]

I actually have strict where that code resides, I just cut out that sub, and excluded strict, but it's in the real script, trust me. dhoss "and I wonder, when I sing along with you if everything could ever feel this real forever? if anything could ever be this good again? the only thing I'll ever ask of you, you've gotta promise not to stop when I say 'when'", she sang	[reply]
