86b4a0b (lists) and fb207c8 (arrays) implement this functionality. The chosen syntax is ,.lst
, not .@lst
(I want to leave @
open so we might use it for decorators or annotations or something in the future, whereas .
at the start of a variable name is already not meaningful). The syntax desugars to unquote-spliced
, similar to how ,
desugars to unquote
.
Currently, we can unquote spliced into lists and arrays. We cannot unquote spliced into vectors, nor can we unquote spliced directly into a quasiquote (i.e. `,.
is always invalid). Currently, we cannot unquote spliced into dictionary literals { ... }
but that may change in the future (see #38).
We have quasiquoting (backtick) and unquoting (comma). We need unquoting spliced (
,@
).Assuming the variable
lst
contains the list(2 3)
, we should get the following results. The first is already working. The second is the subject of this issueIt is an error to use
,@
on a value which is not a list. (or, possibly, a vector; we may choose to allow vectors).
