02-loop.md file - explanation of loop variable names does not mention limitations on the names

[sgenie68]

What's in a name? part mentions that any name can be used as a loop variable. IMHO it is worthwhile mentioning here that there are certain rules and limitations on naming the variables even if these rules and limitations are mentioned someplace else. An important thing to consider would be case sensitivity, for one. Also, the scope of a loop variable would be worthwhile mentioning, too - it may lead to confusions.

Also the list named 'list' is confusing as it's a key word, and it's not explained in the material. what about renaming to element_list, or elements?

+1 for introducing the concept of reserved words/tokens.

Also, @aliceminotto FYI the variable named list has been renamed so it is no longer conflicting with a reserved word (see d7c4b61 )
