Dreams about new generation Bash syntax

1. Compatible with bash code

Features

• indentbased, memorizable, coffeescript-inspired syntax
• removes semantic noise like { ! @ || ~=
• safetynets: automatic quoting, halt on error or missing dependency (require_cmd)
• comfort: json, easy arrays, easy async, functional programming, named variables instead of positionals
• Modules / bundling

Use vars without quotes

Drop any qoute hell: make qoute arg optionally.

if [ $1 = "Hello" ]

always correct, ever when $1 is empty

Function arguments

[function] funcname(arg1, arg2) {
    echo "First arg: $arg1, Secord arg: $arg2"
}

funcname "Hello" "second!"

Global and local variables

All vars are local by default.

use global [readonly] varname for define global var;

Function return value

funcname(arg1) {
    return "text: $arg1"
}

$str = $(funcname Hello)

funcname(arg1) {
    [ "$arg1" = "Hello" ]
}

funcname Hello || echo Bye

if

Use usual

if ($a > $b)
if ($a == $b)
