variable and tie

[Gianmaria Lari]

I would like to tie the last note contained in a variable like this

\version "2.19.81"

var = {a b a}

{\var ~ a}

but this generates an error. This is just a simple example, the reason why I would like to do this is because the variable in the real piece is used many times without the tie except in one case where it has to be tied.

At the moment I do this

\version "2.19.81"

var = {a b \tag #'lastnote a}

{\removeWithTag #'lastnote \var a ~ a}

but I would like to know if there are other solution (maybe better?).

Thank you, g.
