How to use [strings.concat]

The reference page of strings.concat has its arguments, constraints and declaration.

Concatenates a list of strings into one string. Similar to [strings.join], except it doesn’t take a separating character.

.bar:Bar
strings.concat
   .:Thomas
   .:" "
   .:Hansen
   .:" "
   .:Foo
   .:" "
   get-value:x:@.bar

/*
 * Resulting in "Thomas Hansen Foo Bar" after invocation.
 */
