Is the third bit of advice "don't"? Having spent way too long designing an "implementing" a toy language of my own, my first advice to anyone looking to make a toy language would be "don't".
lol ... the third bit of advice is: it's hard, and takes a long time. And if by some miracle the language becomes popular then you'll end up doing hard time and manual labor (i.e., you'll have to write the manual).
I lifted the manual labor joke from Bjarne Stroustrup.
