Re: -E behavior with stdin script (updated x2!)

Note -E doesn't turn on strict, ~~AFAICT its equivalent is -Mfeature=:all~~.

Update: Sorry, that's not quite right - :all also enables experimental features and features that were removed from feature bundles of later versions, like array_base. ~~I showed a slightly hackish workaround here.~~

Update 2: Here's an improved version that gives exactly the same result as the -E switch:

use Config;
use feature ":$Config{PERL_REVISION}.$Config{PERL_VERSION}";

Ah. I was getting confused. So the least-verbose choices become, I think, `[-Mstrict] -Mfeature=:all -- - <<EOF` to run a stdin script `[-Mstrict] -E script` to run a stringified script `-Mv5.28 {-e script \| -- -}` (as of now) to require a recent perl with all security & unicode fixes, turn on `strict`, and run either a stdin or a stringified script.

The least verbose option would be -MMyDefaults, where you write a module named MyDefaults that sets all the bits as you prefer and then you install that on each system you use :-)	[reply]

`-Mfeature=:all` Sorry, I made a mistake, that's actually not exactly equivalent to `-E`, please see the updates in my node above.	[reply] [d/l] [select]
