Was discussing bad notation in a tutorial with the lecturer today.

Hmm, that just seems like god awful notation. What Mathematical object is that?

Literally, that is the worst notation I have ever seen.
It was in the proof for the Bolzano-Weierstrass Theorem for complex sequences.

I haven't come up with a way of proving that the compact linear operators are a closed subset of the bounded linear operators without invoking some horrible notation like that.

I think by being careful you can WLOG the nasty notation out.

I love the use of "WLOG" as a verb. Excellent

Talking of WLOGing* out notational nightmares, one of my favourite passages from Rotman (regarding the spectral sequences arising from the two canonical filtrations of a bicomplex):

'We have created notational monsters
and (they could be worse; one corner is still undecorated) but the next proposition will replace them with something less ugly.'

In fact, in practice they can be worse since I have seen people talking about morphisms of spectral sequences where one or more arises from a bicomplex thus one does indeed need to 'decorate' the lower left hand corner leaving the poor reader the job of keeping track of five indices.

*Great phrase!

Normally notated as 'why aye', it is a common phrase in the North of England loosely translating as 'yes' but can be used generically as a form of conversational punctuation.

e.g. why-aye-man-pet

It helps that I know a guy in lectures who has a reasonably strong North-East accent.
