-------------------------------------------------------------------------------

'g:algorithm_mnemonics_const_return'       *g:algorithm_mnemonics_const_return*

Gives ability to add 'const type qualifier' to returning type.

Values:
  "None"  - don't add 'const'        => 'auto'
  "Left"  - add 'const' to the left  => 'const auto'
  "Right" - add 'const' to the right => 'auto const'
Default: >
  let g:algorithm_mnemonics_const_return = "Right"
<
-------------------------------------------------------------------------------

'g:algorithm_mnemonics_lambda_parameter' *algorithm_mnemonics_lambda_parameter*

Specifies how lambda parameter looks.

Values: string
Default: >
  let g:algorithm_mnemonics_lambda_parameter = "auto const value"
<
