( a * b ) Multiply variable `a` by variable `b`.
.c Take field named `'c'` (string "c" without quotes) from
result of previous expression. Make sense if it was overloaded.
() Call that field.
[ d ] Take field at index stored in variable `d` from result of
.e Same as `.c` before, take field named `'e'` from result of
:f() Take entity at index `f` and call it with single argument
being result of last expression.
