<pre>Description:
It is frequently required to use a single ended bracket such as a brace or
line, but the formula editor requires you to use brackets in pairs, which
changes the meaning. For example to indicate a function evaluated at a point
use a single line to the right followed by the point variable in subscript.
Currently this is not possible. Doing anything in bra-ket notation is not
possible.
Steps to Reproduce:
1. Open formula editor
2. Try to create a single ended bracket such as ... partial over { partial x^i
} right lline _p
3. Drop head to desk
Actual Results:
The entire formula gets messed up if you dont include both brackets.
Expected Results:
We need a single sided bracket, any type of bracket, any side, anywhere. The
insistence on brackets appearing in pairs makes an invalid assumption that they
should (notationally) always be paired (try doing anything in bra-ket notation
for example).
Reproducible: Always
User Profile Reset: No
Additional Info:
Although only one bracket will want to be displayed, the interpreter still
needs to pair these off as they are required to scale. A couple of options for
this could be
1. Begin with the declaration of the bracket that should appear to the right
single right lline { partial over { partial x^i }} _p
2. Another might be to write them both but hide the first
hidden left lline partial over { partial x^i } right lline _p
3. Bra-ket notation is common enough to be given special treatment i.e. have
special constructs for these items
