+Types in r5rS:
+----------------------------------------------------------------
+boolean, symbol, char, vector, pair, number, string, port, procedure
+
+for numbers, the tower goes
+
+ { number { complex { real { rational { integer }}}}}
+
+
+Useful mechanics things (from manual/refman.txt):
+----------------------------------------------------------------
+I think a lot of these are r5rs
+
+(type x)        
+    returns the type (eg, *vector*)
+
+(type-predicate x)
+    returns a predicate that returns true for objects of the same type
+    as x
+
+(arity p)
+    what it sounds like when p is a procedure
+
+(structure? x)
+    predicate for structured objects
+
+(sigma f low high)
+    sums over integers inclusive form low to high
+
+Mechanics package primatives (?):
+----------------------------------------------------------------
+number, vector, matrix, function
+
+unary operators go like ((U f) x) = (U (f x))
+
+binary operators go like ((B f g) x) = (B (f x) (g x))
+
+operators are functions that are "sticky" and act like multiplication?
+
+the primative types might actually be a symbolic expression which would return
+the same type, eg (*number* (sin (+ 4 'b)))
+
+Other mechanics structures (?):
+----------------------------------------------------------------
+
+(up 1 2 3)
+    "up" tuple
+
+(down 4 5 6)
+    "down" tuple
+
+(matrix-by-rows '(1 2 3) '(4 5 6) '(7 8 9))
+    M by N matrix
+
+(series 0.5 0.4 0.3 0.2 0.1)
+    power series with the given coefficients. serieses can be finite or streams
