'One

A Poem

A Raven

Midnights so dreary, tired and weary,
Silently pondering volumes extolling all by-now obsolete lore.
During my rather long nap - the weirdest tap!
An ominous vibrating sound disturbing my chamber's antedoor.
"This", I whispered quietly, "I ignore".'

I hadn't come across it before! and I can't work out the constraint followed by the author at all. I'll read it again. :)

Nope - still nothing. I'll retreat to my weekly cryptic crossword, which seems likely to be easier to solve!

It is in standard pilish. The number of digits in each word represent pi.

So, "One A Poem A Raven" is 3(.)1415 ...
