it's great! how fools are invented fortran! anyone using
macroassembler can define macros for any shape of expression and use
them as they need. for example, instead of writing a=b*c+d it's much
easier to define macro

abcd macro a,b,op1,c,op2,d
  mov r1, b
  op1 r1, c
  op2 r1, d
  mov a, r1
endm

and use it. want to assign a=b/(c+d)? nothing can be easier! just
define one more macro!
