I hope that's not intended to apply to

$x = 'beef'; "\U$x"

But if not, you've got some rather kludgy semantics.

Not this. Only for "literal hex" immediately following the \U because
an "\U$x" is of course still meant to equal uc($x).

Rationale: that's how Unicode characters are usually marked.
Well, in Java they seem to use \ubeef.

But if not, you've got some rather kludgy semantics.

If I could think of better search expressions I could try finding
Larry's message on the subject...

Now that's just a weird way to get BEEF.

Yes, I do recall decreeing something like that, but when I decree
something and it doesn't happen, I usually attribute it to lack of
round tuition rather than passive aggressive behavior. Whether or
not that's the case... :-)

I am glad it is not just me that thought that.
When playing with this stuff that is the order I tried them in ;-)
The last (working) one after greping the docs.

Many things can be said of p5p but *passive* aggressive behaviour
isn't one them...

not that's the case... :-)
