Hi Steffen,

Good to hear from you. I hope you're well.

There's not support for sequence separation characters for loops, but
there is the EolCollection#concat method. In this case, the following
should do what you want:

[%=class.extends.concat(',');%]

Cheers,
Louis.

Whoops, that should be:

[%=class.extends.concat(',')%]

(semi-colon terminators are omitted in dynamic sections)

Hi Steffen,

In for loops, two additional implicit variables are available:

* loopCount : Integer (starts at 1)
* hasMore : Boolean (false if in the last loop, true otherwise)

Having said this, the concat() method suggested by Louis is still the
most efficient option for the scenario you mentioned.

Cheers,
Dimitris
