Subject: Removing array_shift for optimisation.
X-Git-Url: http://git.silmor.de/gitweb/?a=commitdiff_plain;h=4dc490fbd50ca8bd5a6f1c26ddf03c1bfc2abeb3;p=web%2Fkonrad%2Ftwig.git

Removing array_shift for optimisation.

For example we check if a template and use exception to redirect to a default template

Before : We checked ~1000 times => 100sec due to array_shift
After  : ~1sec
