Very interesting!
So, the meaning of -p is performed by textually including the loop around the actual code, so beginning with "}" will close the -p's while loop, and the final "{" will ballance the closing brace at the end of the expansion.
I never thought about that. I always just figured that built-in looping construct was done on a syntactic boundary, like:
while (<>) {
eval $option_e;
print
}
only done in the parse-tree level, not by simply generating more source text!
So... that's not documented or to be relied on, right?
