Hey,

Thought we could share interesting and weird ml code to test our work. Here is one I came up with:

mlcode

2 is printed

3 is printed afterwards

value <- 1

function increment value <- value + 1

Function call with parens right against the name

increment() print value

Empty lines ignored:

Function call with parens separated by a space

increment () print value

You can change it to test your expression checker as follows (this should print an error saying value2 is not defined or something like that):

```mlcode```
# 2 is printed
# 3 is printed afterwards
#
value <- 1
#
function increment
	value <- value2 + 1

# Function call with parens right against the name
increment()
print value

# Empty lines ignored:

# Function call with parens separated by a space
increment ()
print value

cheers,

Mark
