### Evaluate
Evaluate expressions take the general form of a dollar sign (`$`) followed by some _expression_, which is evaluated by the rules below.
- Should the _expression_ be a string, it shall be evaluated as a dynamic variable lookup by first evaluating the string, and then looking up the given variable.
- Should the _expression_ be a list or a command, it shall be converted to a command, whose output (from the standard output) shall be captured, and split to a list with the shell local variable `IFS` (or the default splitter `\n` (newline, 0x0a)). It should be noted that the shell option `inline_exec_keep_empty_segments` will determine whether empty segments in the split list shall be preserved when this expression is evaluated, this behaviour is disabled by default.

##### Infinite Loops
Infinite loops (as denoted by the keyword `loop`) can be used to repeat a block until the block runs `break`, or the loop terminates by external sources (interrupts, program exit, and terminating signals).
The behaviour regarding SIGINT and other signals is the same as for loops (mentioned above).

### History Event Designators
History expansion may be utilised to reuse previously typed words or commands.
History expansion may be utilized to reuse previously typed words or commands.
Such expressions are of the general form `!<event_designator>(:<word_designator>)`, where `event_designator` would select an entry in the shell history, and `word_designator` would select a word (or a range of words) from that entry.
