It only looks like a function call, but in fact it should be an _magic
object_ that can on the call bind a name to an expression in the current
local scope. I chose `this` because in my opinion it is easily
perceived: `while
this( name = expr ) > 0`  can be readed as  "While this name assigned to an
expression is  greater than zero do..." the same interpretation for `if`

With kind regards,
