Repeatable fields?

[Ian Tegebo]

I believe this has been requested before, but I'd like to have repeatable fields.  In reading the code, it appears that one would need to adjust linkages between fields as code seems to assume a fixed number and ordering between fields.  Are they somehow already available?  If not, has anyone any deeper insight into implementing them?

For example, consider switch/case statements:

https://docs.oracle.com/javase/tutorial/java/nutsandbolts/switch.html

I'd like to have a snippet that allows a flexible number of cases.  Outside of Java, consider Common Lisp; a variety of macros take a variable length sequence of expressions often terminated by some boilerplate:

The usual way to do this is to just have a snippet for case. :)

There's a way to do optional else clauses by letting the user either tab past, or delete a variable defaulting to the else part, see https://joaotavora.github.io/yasnippet/snippet-development.html#sec-3-9 (Nested placeholder fields)
