I used to think the \ell was just another funny symbol until I started
studying topology. Now I find that $\ell^2$ is the standard symbol
for a special infinite dimensional topological space which figures
prominently in mathematics. When \ell is not serving this special
role I see it crop up in other places in geometry and analysis.
