Re^3: A short whishlist of Perl5 improvements leaping to Perl7

Perl probably inherited undeclared variables from Awk and shell, both of which create variables when they are set, in contrast to C, which requires all variables be declared with types.

I agree with the origins; I just wish that Perl had rolled a `no strict;` into `-e` rather than providing no constraint on variables in proper scripts. #11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.	[reply] [d/l] [select]

The "original sin" was backwards compatibility to Perl 4, which had no `my` or `strict` . Back in the time piggybacking private variables had huge advantages, but it led to paradoxes, complexity and mounting technical debt.
