That is what I've figured out.
But it is unclear from the parsing what from these is allowed:
int v, w;
...
gang(26)
gang(v)
vector(length: 16)
vector(length: v)
vector(16)
vector(v)
worker(num: 16)
worker(num: v)
worker(16)
worker(v)
gang(16, 24)
gang(v, w)
gang(static: 16, num: 5)
gang(static: v, num: w)
gang(num: 5, static: 4)
gang(num: v, static: w)
and if the length: or num: part is really optional, then
int length, num;
vector(length)
worker(num)
gang(num, static: 6)
gang(static: 5, num)
should be also accepted (or subset thereof?).
