Dear monks,

I have been having trouble finding (imho) satisfactory documentation for the map function.

For example, this, just doesn't tell me what I want to know in a way I can unambiguously understand it. For example, the opening line,

Description: Evaluates the BLOCK or EXPR for each element of LIST (locally setting +$_ to each element) and returns the list value composed of the result +s of each such evaluation
with its sort of circular definition of 'evaluation', makes me look ahead at the examples for clues, but the examples seem too obscure.

(1) Is it just me? Do other people find this documentation clear enough?

(2) Can anyone provide a link to better documentation of this function (or suggest an alternative way to document it)?

Update: After about the fifth time reading through it, I finally understood it, although I am still interested in others' opinions.

Thanks in advance!

to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
