* block internal
block(a,b,c) groups a,b,c and only returns the last arguement as its
value, or returns the second last arguement as its value if the last
arguement is local(). It is used as grouper in definition of a procedure.
All variables in block are global, except for variables declared by
local().
e.g. f(x_):=block(p:=x^6,p, local(p))
See also: local.
