Chapter 6. Expressions Examples: The define expression is used in a pragmatic way, in order to make the reader aware of the fact that the value of the expression depends upon the global variable. This can be illustrated by a small example: ✞ ✡✝ def user = lib(copy) in if user = then true else false where copy is defined in the context, lib is global variable (thus lib(copy) can be considered as looking up the contents of a part of the variable). The operation GroupRunnerUp expl in section 13.1 also gives an example of a define expression. ✆ 6.3 Unary and Binary Expressions Syntax: expression = . . . | unary expression | binary expression | . . . ; unary expression = prefix expression | map inverse ; prefix expression = unary operator, expression ; unary operator = ‘+’ | ‘-’ | ‘abs’ | ‘floor’ | ‘not’ | ‘reverse’ | ‘card’ | ‘power’ | ‘dunion’ | ‘dinter’ | ‘hd’ | ‘tl’ | ‘len’ | ‘elems’ | ‘inds’ | ‘conc’ | ‘dom’ | ‘rng’ | ‘merge’ ; map inverse = ‘inverse’, expression ; binary expression = expression, binary operator, expression ; binary operator = ‘+’ | ‘-’ | ‘*’ | ‘/’ | ‘rem’ | ‘div’ | ‘mod’ | ‘**’ | ‘union’ | ‘inter’ | ‘\’ | ‘subset’ | ‘psubset’ | ‘in set’ | ‘not in set’ | ‘ˆ’ 45
