Conditions

A condition is represented by the if keyword:

let a = 10
if a > 5 then
    print "a is bigger than 5"
else
    print "a is small"

In LENS, the condition statement can be used as an expression:

var stmt = if a > 5 then "bigger" else "smaller"

When used as an expression, the condition must fulfill the following requirements:

• The else clause must be specified
• The expressions returned by both cases must be compatible
