I'm revivifying legacy code but don't have time to refactor it, so I'm looking for a hack. Current code is one single (huge) script using strict that declares all its "global" variables using "my". I am unwilling at this point to change this.
I need a way to modularize the code, while maintaining the lexical scope to the main:: namespace.
In short, I want a pre-compile "include" as opposed to a runtime "require" or a compile-time "use", because those all do not have visibility into the main namespace, or at least AFAIK.
I thought I could get there with do "$file" or eval "cat $file" but the do form still doesn't see my main:: namespace variables and the eval "cat $file" simply fails silently and I don't know why.
I realize that this is a hack, and you will be inclined to say "use packages, proper namespaces and modules" but I don't have time.
I'm sure there's a way to simply include code from an external file as though it were directly injected into the current script. What am I missing? Ozo - I'm expecting you to weigh in here :)

I personally found it overly complex, dismissive and ultimately not that helpful, but it's still a very good reference. Make of it what you will.

eval `cat $filename`
note: the backticks appear to be required.
