Add function expr parsing * Introduce new `fn` keyword * Function example is added to examples/expr.not Signed-off-by: Alek Ratzloff <alekratz@gmail.com> 2020-09-18 16:39:06 -07:00			`# pow = fn (n, p) {`

Add hypothetical "pow" function syntax includes function declaration syntax + ternary expression syntax Signed-off-by: Alek Ratzloff <alekratz@gmail.com> 2020-09-17 13:31:41 -07:00			`# }`

Add rerun_except crate, and small example code * rerun_except will ensure a build doesn't rerun if a .not file is modified, which it would otherwise do Add examples/expr.not with some basic assignment statements and function calls Signed-off-by: Alek Ratzloff <alekratz@gmail.com> 2020-09-17 13:26:38 -07:00			`kilo = pow(2, 10)`
