Syntax

$<LIST:JOIN,list,glue>

Added in version 3.27.

Converts list to a single string with the content of the glue string inserted between each item. This is conceptually the same operation as $<JOIN:list,glue>, but the two have different behavior with regard to empty items. $<LIST:JOIN,list,glue> preserves all empty items, whereas $<JOIN:list,glue> drops all empty items from the list.
