+TYPE PREFIXES
+
+Those have to be prefixes in order to be honored by DOLLSYM:
+[$1norm] should expand to [fnorm], [lfnorm], [#norm], etc.
+
+Those prefixes are necessary in order to achieve polymorphism through
+abstraction arguments.
+
+CURRENT:
+  f   float
+
+FUTURE (from PureData):
+  ~   signal
+  s   symbol
+  p   gpointer
+  a   anything
+  l   list (of whatever)
+  lf  list of floats
+  ls  list of symbols
+  lp  list of pointers
+
+FUTURE (from DesireData):
+  t   stringpointer
+  L   listpointer
+  v   varpointer (instance symbol)
+
+FUTURE (from GridFlow):
+  #   grid (of whatever)
+  #b  grid of bytes (uint8)
+  #s  grid of shorts (int16)
+  #i  grid of ints (int32)
+  #l  grid of longs (int64)
+  #f  grid of floats (float32)
