engine ... a rather old bit of traditional font lig related code

not really as i have no clue how he implements math alphabets (context 
doesn't support such ligatures at all in pure math mode); when wrapped 
in e.g. an hbox the normal font handlers kicks in so there one can use 
any mode (i suppose)
