I have a slight problem. I have some code that is being run inside mason and I have a preprocessing step that transforms strings in mason pages that look like:

  "<I18N id='1007'>I have <I18NARG pos='1'>$foo</I18NARG>KB left to transfer</I18N>"

These get processed into the language appropriate string before the compliation step. So what perl sees (for the default US-english locale) is:

  "I have $fooKB left to transfer"

Which causes a perl compilation error (because of use strict. To fix this particular instance of the problem I can say:

...<I18NARG pos='1'>${foo}</I18NARG>...

But that is not really clean. I would like the translating code to be able to insert a token to protect the variables automatically. The following works, but requires an extra variable interpolation:

my $EMPTY = ""; ... "$foo${EMPTY}KB"

Can anyone thing of some way to insert something into the string that will not actually get inserted into the string yet will cause a variable name to terminate?

Thanks,
