 Strings can be concatenated with <code>&</code>.

+Strings can be concatenated as arrays and joined with separating characters:
-<lang nim>var str1 = "String"
+<lang nim>import strutils
+var str = "String"
-echo(join([str1, " literal.", "HelloWorld!"], "~~"))
+echo join([str, " literal.", "HelloWorld!"], "~~")
 # -> String~~ literal.~~HelloWorld!</lang>
 Strings can be combined using string formatting:
-<lang nim>var str1 = "String"
+<lang nim>import strutils
-echo "$# $# $#" % [str1, "literal.", "HelloWorld!"]
+var str = "String"
-# -> String literal. HelloWorld!</lang>
+echo "$# $# $#" % [str, "literal.", "HelloWorld!"]
+# -> String literal. HelloWorld!
+# Alternate form providing automatic conversion of arguments to strings.
+echo "$# $# $#".format(str, 123, "HelloWorld!")
+# -> String 123 HelloWorld!
