Oops -- wrong again,
Past contibutors to Kona have identified 9 uses of colon in K:
//// 9 uses of colon: /////////////////
//amend/assignment a[]+:9
//pathological verb/inert assigner for amend/error trap (:)[0;2]-> 2
or .(a;();:;9) or .[=;0;:]
//global assignment {b::x}
//conditional statement :[1;2;3] -> 2, even :[0;1] (brackets don't allow spaces)
//function return {if[x;:10]; :20}
//piece of adverb ': /: \:
//piece of number-verb 0:
//indicate monadic "(+:;-)" "1+*:'a" (not if noun to left or right; ok
to have space "+ :")
//resume (debug)
///////////////////////////////////////
Two items on the bright side --
1) I count 41 uses of colon on the J Vocabulary sheet.
2) Currently, my focus is only on implementing "return" for Kona.
