+ The distribute construct specifies that the iterations of one or more loop
+ will be executed by the initial teams in the context of their implicit
+ tasks. The iterations are distributed across the initial threads of all
+ initial teams that execute the teams region to which the distribute region
+ binds.
+
+ The distribute loop construct specifies that the iterations of the loop(s)
+ will be executed in parallel by threads in the current context. These
+ iterations are spread across threads that already exist in the enclosing
+ region. The lower and upper bounds specify a half-open range: the
+ range includes the lower bound but does not include the upper bound. If the
+ `inclusive` attribute is specified then the upper bound is also included.
+
+ // TODO: the following variables will be defined later
+ `private_var`, `firstprivate_var`, and `lastprivate_var` arguments are
+ variadic list of operands that specify the data sharing attributes of the
+ list of values
+
+ The optional `dist_schedule_var` attribute specifies the schedule for this
+ loop, determining how the loop is distributed across the parallel threads.
+ The optional `schedule_chunk` associated with this determines further
