Re: [dev-context] mathpairs

Hi,

I tested with the latest beta and everything works well.

Can you also add a virtual character for --. Then I can add the mappings 
for


-->, <--.

Others that can be mapped are

::, ::=, -:

for which I am attaching a patch file.

BTW, should we remove the definitions of \colonequals, \equalcolons, and

i'll comment them ... how about the others ..


Thanks.

\coloncolonequals can also be commented (it is 0x2A74). We can also 
create a mathpair for this.


* :: (0x3A, 0x3A) -> 0x2237
* ::- (0x2237, 0x2D) -> 0x2A74.

i can make them into virtual characters if needed .. or do they need to 
be added to unicode (given that we have proof of usage, in that case we 
can ask barbara)


I don't see the usage of other \colon... symbols (at least in my sub-field 
of mathematics). For consistency with others, we can convert them into 
virtual characters.
