UDL assymetric delimiters

[Baksa Péter]

I am trying to define a language that has the usual () and [] delimiters, and also it has [,) and (,]
I tried to set delimiter 1 open ( close ) ] and deimiter2 open [ close ) ] but that doesn’t work.
eg.
range [a, b]
range [a, b)
range (a, b]

Ideas anybody?

@Baksa-Péter

can be achieved by using the special operator (( )).
From the document

So, if two or more strings are defined inside of a special operator (( )), they are interchangeable.

so a open like (( ( [ )) and a closing like (( ) ] )) sholud do the trick
