; started thinking about something like set-words get-words in factor (like rebol has)
; which enables you to steal (set) values from middle of flow (function pipeline) 
; in case you need to reuse it later
; :set-word  --- like "set-word" set now
; get-word:  --- like "get-word" get now
; :word -> #word --- so word definition has to change

; rebol example -- couldn't find any better at this time (you see I am using that r: in the middle of expression... 
; it sets r word and passes value forward
show-payment-history: func [ user /local R ] [
	html-table rejoin [ 
		html-table-row [ "Številka predračuna" "Številka računa" "Datum" "Mesecev" "Datum" "Znesek" "Plačano do" "Opombe" ] "th"
		either not empty? r: accumulate x acc copy "" (get-user-data-of "payments" user) [ 
				join acc html-table-row reduce [ x/order-id x/inv-id (get-plan-name x/plan) x/months x/when x/amount x/payed-to x/notes ] "td"
		] [ r ] [ wrap wrap "No payments yet." "td colspan='8'" "tr" ]
