Grouping capabilities?

[shurane]

It would be kind of nifty if there was a way to group lines together in the same 'group'. This way, you could do operations on the group, i.e. sum.

I was thinking about this while trying to break down the amount of work someone had to do for their college classes/jobs/etc.

Example with some syntax:

168 hours * 60 minutes a week = 10,080 minutes a week
#work {{
4 * 60 minutes weekdays + 6 * 60 minutes weekend = 600 minutes
12 * 60 minutes library + 8 * 60 minutes IT support = 1,200 minutes
}}
{#work.righthand.sum} minutes of work

#classes {{
3 * 50 minutes + 2 * 75 minutes calculus III = 300 minutes
3 * 60 minutes discrete mathematics = 180 minutes
3 * 60 minutes communications = 180 minutes
3 * 60 minutes gps \220 = 180 minutes
2 * 75 minutes politics = 150 minutes
}}
{#classes.righthand.sum} minutes of class

#homework {{
5 * 60 minutes * 5 days a week = 1,500 minutes
}}

{#classes.righthand.sum} minutes of classes + {#work.righthand.sum} minutes of work + {#homework.righthand.sum} minutes of homework = 'total' minutes reserved.

Syntax doesn't seem the most ideal, but seems pretty nifty.

I'm reluctant to add syntax beyond 'natural math syntax'. Couldn't you construct these sums by linking? It would be annoying, though.

We're also getting into spreadsheet territory here.
