they have no significant effect on minified and gziped size. in fact
they make things worse.
file | before | after removal
----------------------------------------
concat | 325415 | 325297
min | 62070 | 62161
min + gzip | 25187 | 25176
The bottom line is that we are getting 0.05% decrease in size after
gzip without all of the hassle of using underscores everywhere.
camelcase is used for other angular functions and forEach is also
used by EcmaScript standard.
- rename the internal as well as the external function name
- tweak the implementation of the function so that it doesn't
clober it self when we extend the angular object with an
object that has a forEach property equal to this forEach function
