Maybe not suitable for your usecase, but did you try

«FOR number: numbers»«number»«ENDFOR»

Another option is to use «numbers.join()»

«FOR number: numbers»«number»«ENDFOR» worked. I feel stupid now. I tried this, but not with everything, now when I deleted all breaks it works as intended. I have 360 symbols long method in one row, but its better than weird spacing. Thanks a lot! – Erndob May 12 '15 at 13:52
It's often a good idea to just extract a method for very long expressions. – Sebastian Zarnekow May 12 '15 at 16:59

The for loop construction

«FOR number: numbers»
    «number»
«ENDFOR»

has been mainly created to generates values on many lines. If you need to concatenate values on a single line, join() is a better option:

«numbers.join»

Shorter, cleaner, more clear. And you can also give a separator parameter

«numbers.join(", ")»
