Re^3: Dereferencing a reference to a typeglob?

Thanks for proving my point.

All of this can be handled without manipulating the symbol table or using the *star operator.

Showing advanced techniques like *a=\&func where a function ref is mapped to a special "slot" of a very unique data structure called "typeglob" residing in the symbol table is contra productive for a beginner.

Especially if he just wants to learn dereferencing of lexicals.

It's enough hinting that there are use cases in meta programming Perl.

Thanks again for the provocation.

But I'm not going to play and you already know my opinion about you.

Showing advanced techniques like a=\&func ...* I didn't show that "advanced technique" in either of my posts. You are the only one to use it in the entire thread! ... for a beginner. No where did the OP identify himself as a beginner; nor did anything in his post lead me to believe he was. Especially if he just wants to learn dereferencing of lexicals. And there is the crux of your misreading. He specifically asked about "Dereferencing a reference to a typeglob?" It is, all said and done the title of this thread! So, you misread his question; adjudged him to a beginner on no basis at all; and then condescendingly told him he was asking the wrong question. If my answering the question he asked, and pointing out your error, makes me a "pope troll", then I'll leave it to others to arrive at their own conclusions about your invaluable contributions to this thread.
