This is because it makes you think of control-flow statements in C, which
are special, as you can't define any new (except some macro tricks), and
functions cannot fulfill the same role.
Several languages allow you to define control-flow statements because they
look like any other functions. there are anonymous sub-functions that act
like the blocks of a control-flow statements. In some of those languages,
all control-flow statements are functions.
In Pd, all control-flow statements are objects, and there is no need to
draw a line between "system" and "non-system". There are more useful lines
to draw, such as "behaves like [pack] followed by an object followed by
[unpack]" or "behaves like [timer]", as a way to tell quickly what an
object is supposed to be used like.
