Todo

• Env shorthand
• String interpolation
• Aliases
• Env vars
• Sub commands
• Floats
• Tests
• Decl requires $ but shouldn't
• alias highlighting at call site
• refactor into subcrates
• subcommand alias
• type inference from successful parse (eg not List<unknown> but List<int>)
• parsing tables
• Block params
• Ranges
• Column path
• ...rest without calling it rest
• Iteration (each) over tables
• Row conditions
• Simple completions
• Detecting $it currently only looks at top scope but should find any free $it in the expression (including subexprs)
• Signature needs to make parameters visible in scope before block is parsed
• Externals
• Modules and imports
• Exports
• Support for $in
• Value serialization
• Handling rows with missing columns during a cell path
• Error shortcircuit (stopping on first error)
• ctrl-c support
• operator overflow
• finish operator type-checking
• Source
• Overlays (replacement for autoenv)

Maybe:

• default param values?
• Unary not?
• let [first, rest] = [1, 2, 3] (design question: how do you pattern match a table?)
