In attempting to answer for this, I reached for
curly-braces-expansion but discovered it didn't work as expected:

:let i=3
:let @{i}=''
:echo @{i}

returned an E18 (on the let) and an E15 (on the echo). If I issue

:let i=3
:let x{i}=42
:echo x3

it works as expected. Reading up at

:help curly-braces-names

doesn't give me much insight. Any takers to tell me it's a bug
or point out my misunderstanding?
