- assignment
|

. can argument shadow variables?
|
||||
. yes, why not
|
||||
. no, it's confusing
|
||||
. static errors when variables are missing {{}}, even if recipe isn't run
|
||||
. add tokenizing test that covers interpolation
|
||||
. use the same rules as rust: https://doc.rust-lang.org/reference.html#string-literals
|
||||
. \xHH, \u{HHHHHH}, \n, \r, \t, \0, \\, \{ no other escapes

. '' strings with no escapes

.re-order evaluate assignment
|
||||
- do proper handling of the state stack at EOF
|
||||
- disallow unused arguments and variables
|
||||
- allow exporting environment variables
|
||||
- write some tests to test the binary itself and all command line flags
