[Immanuel Normann <address@hidden>]

Hello,

I would like to have a convenient generic macro (or xmacro) that takes one 
argument representig an infix operator and arbitrary many successive 
arguments representing the operands of tht operator; e.g.:

<generic-infix-macro|+|4|2|5> should expand to "4+2+5"

I know the TeXmacs help page on "Macro primitives" where a very similiar 
example of application is given:

<assign|comma-extra|<macro|x|, <arg|x>>>

<assign|comma-separated|
  <xmacro|args|
       <concat<arg|args|0>
                    <map-args|comma-extra|concat|args|1>>>>>

Where <comma-separate|a|b|c> expands to "a,b,c"

However this example unfortunately does not solve my problem, since you 
can't pass "comma-separated" the "comma" as argument (representing the 
infix operator in this case).
And it is very awkward to write always two macros in the pattern of 
"comma-extra" and "comma-separated" for every infix operator. And one 
needs infix operators with arbitrary operands quite often.

Cheers,
Immanuel
