in thread I don't use printf enough

I'm amazed.

I've long seen @{[stuff]} used for interpolation, but that saves only one character over interpolation (5 vs 6 chars), is unclear, and puts stuff into the wrong context.

By contrast what you've pointed out takes 4 characters, is unclear, but puts things in the right context. However it is a bit fragile.

I wonder why I haven't seen this pointed out before?

I'll definitely be remembering this, if for no reason than golf. But while I prefer it to the @{[...]} interpolation method, I still prefer concatenation over both.

UPDATE: Reminder to self, always test assumptions...

    I'm not sure I understand your comments about @{[ $o->m() ]} putting things in the "wrong" context and ${\ $o->m() } putting things in the "right" context. The method is called in list context in both cases, right? What am I missing?

    I thought, that if you needed scalar context, you had to use scalar(). Perhaps ~~ if you are golfing and can get away with it. (I.e. your method isn't returning a reference or a floating point number.)

    Heh . . . ${\~~$o->m} . . . Ick! :-)

    Edit: Added the text "or a floating point number."
