There's a for-loop, with three expressions (sometimes called "C-style for").

There's a foreach-loop, with single scalar (sometimes implied with $_) and a list of values to be walked (sometimes called a "csh-style foreach").

They're definitely two different kinds of loops. However the text for and foreach may be used to introduce either one. The actual loop-style is determined by what follows.
