Programming Languages Side By Side

This will show concepts and constructs in Perl, Ruby, and (...?) in a side-by-side comparison.

Very rough right now, so don't count on it for accuracy yet.

	Perl	Python	Ruby	VisualBasic
white space	required to separate words from other words; optional otherwise	required to define blocks and their nesting levels? and to separate words from other words?	required to separate words from other words; optional otherwise?	enforced by the IDE; optional additional spaces allowed for readability
comments	`# comment...` (to eol)	`# comment...` (to eol)	`# comment...` (to eol)	`; comment...` (to eol)
block defs	`{ ... }`	defined by additional levels of indentation: must be equal amount of spaces/tabs in front of each line at a given block level	`{ ... }`	defined by specific statements; indentation done automatically by IDE
arrays/lists	`['sample', 1, 2, 'strings allowed']`	`['sample', 1, 2, 'strings allowed']`	`['sample', 1, 2, 'strings allowed']`	`Array('sample', 1, 2, 'strings allowed')`
array elements	`@array = ['a', 'b', 'c']; $array[0]` → `'a'`	`array = ['a', 'b', 'c'] array[0]` → `'a'`	?	?
array slices	`@array[0,1]` → `['a', 'b']` `@array[0,2]` → `['a', 'c']`	`array[0:1]` → `['a']` `array[0:2]` → `['a', 'b']` `array[1:3]` → `['b', 'c']`	?	?
conditional blocks	`if (a < b) { # ... } elsif (a > b) { # ... } else { # ... }`	`if a < b: # ... else:` `if a > b: # ... else:` `# ...`	?	`If a < b Then ; ... ElseIf a > b Then ; ... Else ; ... End If`
