Do you plan for conditional code in macros?

Question

Is it possible to define parts of the macro conditionally? If not, is there any workaround for this? In the example below the macro is generating different output, which is controlled by parameter c.

@startuml

!define LAYER1 1
!define LAYER2 2

!definelong TEST_MACRO(a, b, c)
if c
a->b: defined c
endif
!enddefinelong

TEST_MACRO(a, b, LAYER1)
TEST_MACRO(c, d, LAYER1 | LAYER2)
TEST_MACRO(a, b, LAYER3)

Yes, this functionality described on wiki is everything what I need. When do you plan to release it?

There is no time frame discussed when to implement it. The first step is to discuss it thoroughly, afterwards it can be planned and implemented. So most likely not in the next release(s).

No time frame indeed. However, we have begun to implement some stuff.
It's only a beginning, more details on http://wiki.plantuml.net/site/plantumlshell
