manual: Update Attribute Set section to exclude indented strings and URIs
Indented strings and URIs are string literals but they are not allowed
as names for attrsets, `let` or `inherit`. The following snippets
illustrate that they lead to syntax errors.
==> examples/ind_str-attr.nix <==
{
''indented string'' = "error: syntax error, expecting '}'";
}
==> examples/ind_str-inherit.nix <==
{ inherit ({ "non-indented string" = "error: syntax error, expecting ';'"; })
''non-indented string'';
}
==> examples/ind_str-let.nix <==
let
''indented string'' = "error: syntax error, expecting 'in'";
in
true
==> examples/uri-attr.nix <==
{
http://example.org/foo.tar.bz2 = "error: syntax error, expecting '}'";
}
==> examples/uri-inherit.nix <==
{ inherit ({ "http://example.org/foo.tar.bz2" = "error: syntax error, expecting ';'"; })
http://example.org/foo.tar.bz2;
}
==> examples/uri-let.nix <==
let
http://example.org/foo.tar.bz2 = "error: syntax error, expecting 'in'";
in
true
