Thanks,
Is there a resource covering the rules for variables, values and functions? I
am still somewhat confused because if I define func = x: x=="x" I do not need
to antiquote with ${}.
Cheers,
Matan

When you write "attset.at", it means " search for key named 'at' in the set".
'at' is not considered as a variable but as a value. If you have a variable,
you first have to ask Nix to replace your variable by its value.

That should be:
pick = at: attset: if (attset ? ${at}) then [ attset.${at} ] else []
Note ${...} around "at". Otherwise it tests for an attribute named "at".
