[Bug-apl] element

[Egan Ford]

Hi, first off, thanks for GNU APL.

Not a bug, just an FYI.

I am new to APL and still learning.  I had to make the following
change to use Dyalog keyboard maps for OS/X as well as cutting and
pasting examples from wikipedia and other sources.

//char_def(ELEMENT            , 0x2208 , F12_ELEMENT  , NO_SPACE ,  EE) /* ∈ */
char_def(ELEMENT            , 0x220A , F12_ELEMENT  , NO_SPACE ,  EE) /* ∊ */

Personally I like 0x2208 I will change the keymaps.
