Foreach()

FOREACH()

 FUNCTION: foreach([<object>/]<attribute>,<string>[,<begin>, <end>])

 Maps a function onto a string.

 Each character in <string> has the user-defined function of the first
 argument performed on it; the character is passed to the function as
 %0. The results are concatenated. If <begin> and <end> are specified,
 only the characters between <begin> and <end> are parsed, other characters
 are concatenated as they are. This allows a rudimentary form of tokens and
 speeds up the evaluation greatly if tokenizing is your purpose.

 Examples:

   > &add_one me=[add(%0,1)]
   > say [foreach(add_one, 54321)]
   You say, "65432"

   > &add_one me=[add(%0,1)]
   > say [foreach(add_one, This adds #0# to numbers in this string,#,#)]
   You say, "This adds 1 to numbers in this string."
